Hi Res Adventures

Hi-Res Adventures is a series of graphic adventure games developed by On-Line Systems. It includes all seven graphic adventure games released by the company prior to the release of the company's landmark King's Quest. Mission Asteroid was meant as an introduction to the adventure game genre so it was made easier than the rest of Hi-Res Adventure games and was given a lower number as a result even though it was released after Mystery House and Wizard and the Princess.
