Battlefield 3 Beta - Absoluuuuuute gaaaarbage son, do yourself a service and don't play it. I'm not saying the full game will be this bad but the beta is terrible. Its a slow paced campfest, where you spend like 1/4 of the time running looking for enemies, and most of your deaths are assholes camping in bushes or just randomly prone in a hard to see area. I know some of my hate for this game comes from my preference of run and gun games (CoD, Killzone, Halo, etc.) but there are better tactical games out there than this if thats what you like (Rainbow Six Vegas 2 for example)
NHL 12 - Overall its a great game but there are many things I'd change about it to make it better. I like the fact that goalies are now like actual players in that they can be checked but it leads to soooooooo many goalie interference calls that aren't really your fault (like you get nudged into the goalie by an opposing defender and you get called for it), another thing is since they've nerfed hitting (especially the hipcheck) in the last update it's made defending a LOT harder. I'm glad they changed hipchecking because it was way OP but now its un-usable. The only option left on defence now are poke checks and stick lifts which make lead to many tripping/high sticking penatlies. And then the AI is really bad in online team play, they give shit passes and make stupid plays all the time. Although I have many complaints its still a decent game.
GTA IV - I got the DLC's for it about a month or two ago and that's revived my interest in the game. Lost and Damned is garbage but the Ballad of Gay Tony is well worth the cost. It adds a lot to the online such as good new weapons, new cars, and a parachute for base jumping or jumping out of helicopters. Its well worth the purchase.
Modern Warfare 2 - Yeah I went back to this "classic" after I quit Black Ops. If you get a lobby with no noob tubers, commando knifers or 1337 Grizz OpTic Kwiksc0perzz then its a fun game, but 90% of the time lobbies are full of straight assholes that use in game exploits to make everyone else annoyed. Can't wait till MW3; no commando, noob tubes are nerfed (no danger close + there is a blast shield perk like Flak Jacket in BO) and an overhauled killstreak/pointstreak system.
Those are what I'm playing now. I'm soooo bored with my current games. MW2 is bad, BF3 beta is bad, NHL 12 is fun in small doses (gets frustrating fast if you keep losing), and GTA4 is great but I'm not playing it as much anymore. I can't wait for Forza 4 in about 2 weeks.
