GTA IV - Fun and alive, amazing in many ways. Controls still not perfect ;(
MAFIA - Finally tried this. It was fun, but I didn't finish it. Lacked the freedom of GTA.
SUPER MARIO GALAXY - AMAZING! Constantly suprising, adding new wonderful things at every turn.
BOOM BLOX - Wow. Did not expect anything from it, but it's fun, fun, fun.
GUITAR HERO 1, 2, 3 - Still playing these. Especially with friends. It's addictive.
PHOENIX WRIGHT; AND JUSTICE FOR ALL - Not sure it was as good as the first one. Definatly wonderful though
ASSASSINS CREED (PC) - Hmm... It's fun to climb, but a bit too easy. It's somewhat fun to assassinate people. The rest is just boring.
PORTAL - Still picking up this game from time to time. Last years best game, without a doubt.
WII SPORTS - Great party-game!
Hmm... Haven't been playing a lot lately. I've been reading instead. Finished around 15 new books and re-read more than that.
