Windowed games that you can alt-tab out of/hide quickly are better, playing huge games like Oblivion would take a while to minimize, especially on school computers.

We also had a little program that would hide that bar on the toolbar using hotkeys.
Ah, good times.

LF2 is fun with friends.

FNugget, you are amazing that was the perfect post.

Sumotori Dreams is a very cool and funny game!!! I hope they continue to update it!
