This is a game I have been working on off-and-on for a long time. You fly a spaceship and blow up other spaceships. Content is procedural, although the variety and danger level increases over time. There is no end condition except dying, but there is about 3 hours worth of discoveries. By the end, there are about 100 types of enemy ships and more than 60 types of pickups, only one of which is "more damage".
