I know for a fact that this community is big on games. This thread is devoted to your favorite freeware games of all time. I'll start off with mine:

Torus Trooper (http://www.asahi-net.or.jp/~cs8k-cyu/windows/tt_e.html)

This is a cool little Japanese-style shooter where you pilot a little ship through a never-ending course full of enemies. The vector graphics are not only a nice effect, but end up looking pretty good to look at too. In this game, you don't have lives, but a time limit. Everytime you die, you loose 15 seconds. Everytime you destroy a boss or advance to a particular part of a level, you gain time.

Little Fighter 2 (http://home.hkstar.com/~marti/)

This is a bit of an oldie, but a goodie. This cute fighting game packs a lot of characters (including a few hidden ones), a story and battle mode, and special moves. You can play with up to 4 players on one keyboard, but it also has online play too, allowing up to 8 players to battle it out at once.

America's Army (http://www.americasarmy.com/)

America's Army is a popular online first person shooter that puts you right in the virtual battlefield.

Grand Theft Auto 2 (http://www.rockstargames.com/classics/)

This is a game that needs no introduction. Experience GTA pre-Liberty City.
