My memory is kinda fuzzy too but I believe Star Control was the never ending one(or close to it). I know for sure starflight had a "save the universe or die" kind of plot. If you didn't figure out how to beat it by a certain time it just ended. Maybe things changed once you beat it but I don't remember that.
Btw Star Control is one game I wanted to spend a lot of time on but couldn't. I never owned a 3DO but my friend had one. Until one day when someone put glue in the disc tray and ruined it. It was a sad day I tell you what.
