Some good games; no real priority, nothing stood out as "dammit beyond dying you must play this". Bugger me so many sequels though...
Metro 2033 - Not finished the SP yet, for goodness knows what reason, it's like the last level. Still utterly fun though up to that point.
Bad Company 2 + Vietnam - Late to the party, but loads of fun in multiplayer. The SP is passable and helps you to learn the weapons a bit. Vehicles, large maps and always team based gameplay with no silly perks appeals. One issue is the stupid levelling system, go go gimped new players...urg.
Dawn of War 2: Chaos Rising - Excellent expansion pack since I thoroughly enjoy the singleplayer; just so over the top action. Can be quite hard too which is great.
Fallout: New Vegas - Everything Fallout 3 fell down on (factions interacting, banal main plot, out of character factions, some terrible weapon selections and the game being damn easy with insta-stimpacks, and also terrible companions) was improved and bettered. An interesting world with actual fascinating intrigue and a better enemy faction of your choice. Improved massively with a radio mod for more tracks though.
Mass Effect 2 - Fast paced RPG-ness. The combat/RPG levelling was to me oversimplified and the combat, if not especially difficult, was certainly frustrating in places since it is basically only you killing things and you get limited ammo. Still apart from some blatant plot hiccups (bloody idiot shadow man) it had some more fascinating characters and places to visit, and I still love the voiceacting and sheer character of the games. Mining minigame can bugger off though, so much wasted time on that.
BioShock 2 - A good sequel - enjoyable levels, nice upgrades this time (fear my drill and named sentry bots!), a more coherent plot throughout and some very inventive work put into some parts of the game and it certainly is much more fun to play.
S.T.A.L.K.E.R.: Call of Pripyat - A great end to the first set of STALKER games (they're making STALKER 2 now right?), being part of the military gives me the ample canon for a faction I otherwise was fascinated with but never got to talk to, the levels were well tuned and some more demanding decisions being made of the player to actively do one thing or another, rather then general side missions. Was fun to decide what to do; and the AI was great this time (more times you played in a group, was good).
Ace Attorney Investigations: Miles Edgeworth - Like Leftism said, a damn fun game. Not too challenging, but was rewarding and seeing you move around more actively was just more pleasing then static screens. No courtroom drama is a real shame, but it still pulled something similar off, and was much better then the last Ace Attorney game.
Assassin's Creed II - Still playing, but damn it is so much better then the first game. Sadly no skippable cut-scenes still, but they're not hours long either (still a shame if you exit and have to re-watch them again). Extra assassination missions outside of the main plot and more combat moves/enemy types make it very fun; you really feel you have the power to kill anyone this time.
Pokémon HeartGold and SoulSilver - Yes, addictive handheld nostalgic (but still good) play-on-the-bus fun. Best game in the series is still Gold and Silver, and this remake captures most of that again. Now I am just waiting for Black and White...
StarCraft II: Wings of Liberty - Singleplayer == good clean, if very predictable levels (mainly) and utterly unsatisfying plot-wise. MP still makes me wince, and I dare not go back there.
Mount and Blade: Warband - Multiplayer is a damn fun addition to the game actually - the c-rpg mod makes it a wee bit more persistent and less wacky then the normal one (which is still pretty fun). The revised map and actions in the game are okay too - much better then the original, more balanced, and you can become king/queen now, wheee
Got to play more of: Alpha Protocol (why haven't I played this? just...kinda left the disk and never installed it!), Napoleon: Total War, Civilization 5 (this just does not appeal still for some reason; I think I love civ4 that much more) Just Cause 2, Batman Arkham Asylum (I only brought it this year...not even booted it up), Misadventures of P.B. Winterbottom, Professor Layton and the Unwound Future (still playing...is it all a dream again? or is this going to go mental and be actually real?) and others.
Still not brought Golden Sun: Dark Dawn or Super Scribblenauts yet though. I've also played a wee bit too much AI War, League of Legends and Team Fortress 2 from earlier years, heh.
