Space flight simulation game

Realistic simulation

Realistic space simulators seek to represent a vessel's behaviour under the influence of the Laws of Physics. As such, the player normally concentrates on following checklists or planning tasks. Piloting is generally limited to dockings, landings or orbital maneuvers. The reward for the player is on mastering real or realistic spacecraft, celestial mechanics and astronautics.

Classical games with this approach include Space Shuttle: A Journey into Space (1982), Rendezvous: A Space Shuttle Simulation (1982), The Halley Project (1985), Shuttle (1992) and Microsoft Space Simulator (1994).

If the definition is expanded to include decision making and planning, then Buzz Aldrin's Race Into Space (1992) is also notable for historical accuracy and detail. On this game the player takes the role of Administrator of NASA or Head of the Soviet Space Program with the ultimate goal of being the first side to conduct a successful manned moon landing.

Most recently Orbiter and Space Shuttle Mission 2007 provide more elaborate simulations, with realistic 3D virtual cockpits and external views.

Kerbal Space Program can be considered a space simulator, even though it portrays an imaginary universe with tweaked physics, masses and distances to enhance gameplay. Nevertheless, the physics and rocket design principles are much more realistic than in the space combat or trading subgenres.

The game Lunar Flight simulates flying around the lunar surface in a craft resembling the Apollo Lunar Module.

Space combat game

Most games in the space combat genre feature futuristic scenarios involving space flight and extra planetary combat. Such games generally place the player into the controls of a small starfighter or smaller starship in a military force of similar and larger spaceships and don't take into account the physics of space flight, usually often citing some technological advancement to explain the lack thereof. The prominent Wing Commander, Tachyon: The Fringe, X-Wing and Freespace series all use this approach. Exceptions include the first Independence War and the Star Trek: Bridge Commander series, which model craft at a larger scale and/or in a more strategic fashion. It should be noted that I-War also features Newtonian style physics for the behaviour of the space craft, but not orbital mechanics.

Space combat games tend to be mission-based, as opposed to the more open-ended nature of space trading and combat games.

Space trading and combat game

The general formula for the space trading and combat game, which has changed little since its genesis, is for the player to begin in a relatively small, outdated ship with little money or status and for the player to work his or her way up, gaining in status and power through trading, exploration, combat or a mix of different methods. The ship the player controls is generally larger than that in pure space combat simulator. Notable examples of the genre include Elite, Wing Commander: Privateer, and Freelancer.

In some instances, plot plays only a limited role and only a loose narrative framework tends to be provided. In certain titles of the X series, for instance, players may ignore the plot for as long as they wish and are even given the option to disable the plot completely and instead play in sandbox mode. Many games of this genre place a strong emphasis on factional conflict, leading to many small mission-driven subplots that unravel the tensions of the galaxy.

Games of this type often allow the player to choose among multiple roles to play and multiple paths to victory. This aspect of the genre is very popular, but some people have complained that, in some titles, the leeway given to the player too often is only superficial, and that, in reality, the roles offered to players are very similar, and open-ended play too frequently restricted by scripted sequences. As an example, Freelancer has been criticised for being too rigid in its narrative structure, being in one case compared negatively with Grand Theft Auto, another series praised for its open-ended play.

All space trading and combat games feature the core gameplay elements of directly controlling the flight of some sort of space vessel, generally armed, and of navigating from one area to another for a variety of reasons. As technology has improved it has been possible to implement a number of extensions to gameplay, such as dynamic economies and cooperative online play. Overall, however, the core gameplay mechanics of the genre have changed little over the years.

Some recent games, such as 2003's EVE Online, have expanded the scope of the experience by including thousands of simultaneous online players in what is sometimes referred to as a "living universe"—a dream some have held since the genre's early beginnings. Star Citizen, a title currently in open, crowd-funded development by Chris Roberts and others involved in Freelancer and Wing Commander, aims to bridge the gap between the EVE-like living universe game and the fast action of other games in the genre.

Kerbal Space Program, which has a realistic physics simulation, has some characteristics of a space trading game in some way. For example, it includes a career mode, in which spaceship parts are unlocked through "Science" and has funds, contracts and a reputation system.

An additional sub-class of space trading games eliminate combat entirely, focusing instead entirely on trading and economic manipulation in order to achieve success.

Space flight games

Most modern space flight games on the personal computer allow a player to utilise a combination of the WASD keys of the keyboard and mouse as a means of controlling the game (games such as Microsoft's Freelancer use this control system exclusively). By far the most popular control system among genre enthusiasts, however, is the joystick. Most fans prefer to use this input method whenever possible, but expense and practicality mean that many are forced to use the keyboard and mouse combination (or gamepad if such is the case). The lack of uptake among the majority of modern gamers has also made joysticks a sort of an anachronism, though some new controller designs and simplification of controls offer the promise that space sims may be playable in their full capacity on gaming consoles at some time in the future. In fact, X3: Reunion, sometimes considered one of the more cumbersome and difficult series to master within the trading and combat genre, was initially planned for the Xbox but later cancelled. Another example of space simulators is an arcade space flight simulation action game called Star Conflict, where the players can fight in both PvE and PvP modes.

Realistic simulators

Realistic simulators feature spacecraft systems and instrument simulation, using a combination of extensive keyboard shortcuts and mouse clicks on virtual instrument panels. Most of the maneuvers and operations consist of setting certain systems into the desired configuration, or in setting autopilots. Real time hands on piloting can happen, depending on the simulated spacecraft. For example, it's common to use a joystick analog control to land a space shuttle (or any other spaceplane) or the LEM (or similar landers). Dockings can be performed more precisely using the numerical keypad. Overall, the simulations have more complex control systems than game, with the limit being the physical reproduction of the actual simulated spacecraft (see SimPit ).

History

Early attempts at 3D space simulation date back as far as 1974's Spasim, an online multi-player space simulator in which players attempt to destroy each other's ships.

The earliest known space trader dates to 1974's Star Trader, a game where the entire interface was text-only and included a star map with multiple ports buying and selling 6 commodities. It was written in BASIC.

The modern space flight game genre emerged at the point when home computers became sufficiently powerful to draw basic wireframe graphics in real-time. The game Elite is widely considered to be the breakthrough game of the genre, and as having successfully melded the "space trading" and flight sim genres. Elite was highly influential upon later games of its type, although it did have some precursors, and games similar to Elite are sometimes called "Elite-clones".

Elite

Elite has made a lasting impression on developers, worldwide, extending even into different genres. In interviews, senior producers of CCP Games cited Elite as one of the inspirations for their acclaimed MMORPG, EVE Online. Þórólfur Beck, CCP's co-founder, credits Elite as the game that impacted him most on the Commodore 64. Developers of Jumpgate Evolution, Battlecruiser 3000AD, Infinity: The Quest for Earth, Hard Truck: Apocalyptic Wars and Flatspace likewise all claim Elite as a source of inspiration.

Elite was named one of the sixteen most influential games in history at Telespiele, a German technology and games trade show, and is being exhibited at such places as the London Science Museum in the "Game On" exhibition organized and toured by the Barbican Art Gallery. Elite was also named #12 on IGN's 2000 "Top 25 PC Games of All Time" list, the #3 most influential video game ever by the Times Online in 2007, and "best game ever" for the BBC Micro by Beebug Magazine in 1984. Elite's sequel, Frontier: Elite II, was named #77 on PC Zone's "101 Best PC Games Ever" list in 2007. Similar praise has been bestowed elsewhere in the media from time to time.

Elite is one of the most popularly requested games to be remade, and some argue that it is still the best example of the genre to date, with more recent titles—including its sequel—not rising up to its level. It has been credited as opening the door for future online persistent worlds, such as Second Life and World of Warcraft, and as being the first truly open-ended game. It is to this day one of the most ambitious games ever made, residing in only 22 kilobytes of memory and on a single floppy disk. The latest incarnation of the franchise, titled Elite: Dangerous was released on the 16 of December 2014, following a successful Kickstarter campaign.

Trade Wars

Though not as well known as Elite, Trade Wars is noteworthy as the first multiplayer space trader. A BBS door, Trade Wars was released in 1984 as an entirely different branch of the space trader tree, having been inspired by Hunt the Wumpus, the board game Risk, and the original space trader, Star Trader. As a pure space trader, Trade Wars lacked any space flight simulator elements, instead featuring abstract open world trading and combat set in an outer space populated by both human and NPC opponents. In 2009, it was named the #10 best PC game by PC World Magazine.

Other examples

Elite was not the first game to take flight game mechanics into outer space. Other notable earlier examples include Star Raiders (1979), Space Shuttle: A Journey into Space (1982), Rendezvous: A Space Shuttle Simulation (1982), and Star Trek: Strategic Operations Simulator (1982), which featured five different controls to learn, six different enemies, and 40 different simulation levels of play, making it one of the most elaborate vector games ever released. Other early examples include Nasir Gebelli's 1982 Apple II computer games Horizon V which featured an early radar mechanic and Zenith which allowed the player ship to rotate, and Ginga Hyoryu Vifam, which allowed first-person open space exploration with a radar displaying the destination and player/enemy positions as well as an early physics engine where approaching a planet's gravitational field pulls the player towards it. Following Elite were games such as The Halley Project (1985), Echelon (1987) and Microsoft Space Simulator (1994). Star Luster, released for the NES console and arcades in 1985, featured a cockpit view, a radar displaying enemy and base locations, the ability to warp anywhere, and a date system keeping track of the current date.

Some tabletop and board games, such as Traveller or Merchant of Venus, also feature themes of space combat and trade. Traveller influenced the development of Elite (the main character in Traveller is named "Jamison"; the main character in Elite is named "Jameson") and Jumpgate Evolution.

Decline

The seeming decline of the space flight simulators and games in the late 1990s coincided with the rise of the RTS, FPS and RPG game genres, with such examples as Warcraft, Doom and Diablo. The very things that made these games classics, such as their open-endedness, complex control systems and attention to detail, have been cited as reasons for this decline.

Resurgence

Some recent franchises such as the X series and EVE Online, may end a decade in which no new title of the genre was published. The open source community has also been active, with recent projects such as FS2 Open and Vega Strike serving as platforms for non-professional efforts. Unofficial remakes of Elite and Privateer are being developed using the Vega Strike engine, and the latter has reached the stage where it is offered as a working title to the public.

In November 2012 Star Citizen set a new record for crowdfunding. It has managed to raise more than $114 million as of May 2016. Elite: Dangerous was also successfully crowdfunded on Kickstarter in November and December 2012. Born Ready Games also closed a successful Kickstarter campaign at the end of 2012 raising almost $180,000 to assist with the completion of Strike Suit Zero which was released January 2013. Another open-ended space sim in development is No Man's Sky.

On March 10, 2013, the space flight simulator Kerbal Space Program reached the top 5 best selling games after its release on Steam.
