I had a bunch of games on a really old computer a long time ago.
One of them was Ski Free. Man, I loved that game. It looks like crap, but it has an endearing quality to it.
Another was a TMNT game, a lot like Turtles in Time. That one was also fun, but I can't remember what it was called.
Also, this isn't really a favorite, but I just find it funny it exists: Sneak King.
