Game of the Year. No doubt.

This game from Valve was just a tiny blip on everyone’s radar screen and just a little side-serving next to the big release of Team Fortress 2. But, Portal is a real gem of a game. It’s fun, there’s no killing, and most importantly, it’s hilariously funny and seriously science fiction.

Despite the need for Steam to play the game, it’s well worth the $20 price tag.
