I can't play by myself. I like America's Army. Mostly cause it's free multiplayer. Someone else was showing me a Tetris/Pirate massively multiplayer game that was free, too.
Am I the only Minesweeper fan out there? Playing it on the hardest lever is nuts. Have not played it in about a year though.
hmm. Never been much of a fan of those. I like BF1942. For the freebie game on Windows, I like the pinball game.
