Personally i dont really have a 2012 favorite i simply there was a game that i found that hooked me and made me slobber over myself just to play it when i was outside the house sure there was a couple ones that made passing the time easier and allowed for some fun times with friends online, like Mass Effect 3 while i still havent finished the SP(no hook after a while into it ) the mp was suprisingly fun and friends which who knew nothing about the franchise got into it becuz of the MP, and wow did we get frustrated at times with it, hours of suriving too buy thosse damn boxes just to get a pistol that just tickles the enemy or a mod i dont use or the friggin redo a character thing... then there was Boderlands 2 whose charm and comedy made it a fun ride but it seems its time in the spotlight was cut short with the release of holiday pwerhouses like COd and Halo and for while a there a tried to play solo but like many once the amp shields were changed soloing was too much of a hassle maybe if the increased drops it would be worth it... powerhouse COD came in and everyone on the friends list just crammed into its lobbies and like many i have a love hate relationship with it overall its a good game but once again i think the map layout, spawns, and game balances and reintergration of full quickscoping makes me want to burn the game, not to mention the horrible lag compensation and map count which seriously feels lacking with the amount the gamers have put into the franchise you would hope a couple a free map packs with past game maps would come out as a thank you but no we get 4+1zmb packs again at 15 bucks a pop

but for the sake of this contest and to forget this little rant of mine
ill vote for Mass effect 3 simply as a first try into mp it wasnt bad and most of the available DLC was included at no charge

now lets hope for the next gen to come out as fast as possible see if we cant get some real improvements in gameplay i.e player count in games
