Ratrun

The Good
This was the first 3-D game I ever saw and it blew people's minds that such a thing was even possible even on the most powerful computer available. So cool looking even today!

The Bad
You could see the cheese once you found it, but you could never see the rat. (you were the rat). So frustrating! ;-]

The Bottom Line
Played this in all my free time in the computer lab in high school. I can't believe nobody has ported it to Mac or Windows or phones. It is really challenging to remember where you've been in the maze.
