grand theft auto 4 (PS3) - somewhat disappointed with it so far. the hero of the story is kind of an idiot (he wants to get away from violence and start a new life in america, but gladly goes to kill people without protesting), the girlfriend thing is annoying as hell (maybe in the next installment you have to go to teh bathroom twice a day? more realistic, you know), it seems the option of buying real estate has disappeared (although that might open up later, i'm not done with the game yet), and the mission design is as repetitive as ever. it's basically GTA3 with better graphics... not bad but not what i had expected. maybe it will get better later in the game.
gran turismo 5 prologue (PS3) - excellent arcade racer (i know sony calls it a simlator but that must be a joke on their part), but it lacks the ability to customise cars and there are only a few tracks. teh environments don't look all that good either, but the interior view of the cars is very well done. not worth the 40 bucks though, i should have waited for the full game to come out.
team fortress 2 (PC) - the new map is great fun, but gets repetitive too quickly. i hope valve will make more maps that use the same concept.
