pc- World of Warcraft, Warcraft 3 (blizzard is god)
ps2- GT3 (classic), and going to buy kessen 3 because kessen 2 was awsome despite a few annoying chars

oh and you xbox people should definatly look into a game called Jade Empire its made by the same people who produced kotor and looks alot like it except with more options and it takes place in ancient china i believe my friend wont stop talking about it and i must admit that it sounds pretty cool
