Roommate is by far our oldest computer game. It is a video-adventure game for Windows. In the game you play as a college student and your goal is to get rid of your roommate who is occupying the flat which you would need to be empty for the night out of "personal incentives".
Gameplay is quite short (15 minutes), but branches and actually allows you to lose the game or win by taking a different path.
The game runs on an own engine and is scripted using XML.
