Right now:
BF2 (tons of bugs in this game, and way too many noobs in the ranked servers. Still a good game all in all. Not near as good as BF1942 though.)
Guild Wars (good MMO, but hard to find your way around at first; for me atleast. I still like WoW better though!)
Rome: Total War (awesome battles. that's one thing that just brings this game to life, watching hundreds of men running at each other; and I haven't even gotten to the bigger battles yet!. Having natural disastors destroy half your town is always cool too. If you haven't tried this game and are an RTS fan, you're definately missing out!)
LEGO Star Wars (there's nothing better than kicking butt with these little guys! Awesome mini games and puzzles in every level! Follows movies very well, and adds a level of realism to the game.)
