For my part, I don't really have a "ten best" list, because there have been some really exceptional games this year and I can't remember what all came out when, but some of my favorites this year that don't appear on Tom's list (though I enjoyed all of the games Tom lists that I've actually played - about half - and would probably adore Diablo 3 if it weren't for the DRM that makes it a toxic purchase) include:
The Secret World:
Funcom botched the launch, certainly. There were some really critical bugs, especially surrounding chat, and there are some things that they really should have rethought design-wise (I understand that the factions are theoretically at odds game-fictionally, but when you can quest with literally anyone outside of the handful of dedicated PvP battlefields, cross-faction guilds really, really should have been an option). But it remains a fantastically beautiful, very well written game with a setting that is completely unique among MMOs and very compelling to me personally. The almost ARG-style investigative quests are (mostly) brilliant and again completely unique among MMOs, and the classless skill wheel system turns out to work quite well and scratch the deck building itch that drives so many CCGs. They've also done very well at rolling out consistent content updates despite an unfortunate level of staffing loss, and they just bit the bullet and dumped the subscription requirement.
Dishonored:
A gorgeous, painterly world, smart writing, a densely packed space that rewards exploration, intense combat, and very satisfying movement, stealth, and magical powers.
World of Warcraft: Mists of Pandaria:
Yeah, it's more WoW. But for all that WoW currently represents essentially the baseline MMO, it's also got probably the most content of any MMO on the market, an absurd number of potential activities not limited to the traditional questing, PvP and raiding of most MMOs, gorgeous art direction, more varied quest design than any MMO other than The Secret World, a brilliantly customizable interface (I am an addon addict), and now Pokemon. I don't really know why they chose to add that, nor why they chose to base the current expansion off an ongoing April Fool's joke, but I'm enjoying both thoroughly.
Spec Ops: The Line:
Standard military shooter gameplay, but apocalyptic, sand-choked Dubai and the Heart of Darkness-inspired morality tale of the storyline made for a very memorable game for me. I had honestly not expected this one to pan out, but it did.
Torchlight II:
I enjoy this sort of game, but I don't get really into them, generally speaking. I'll beat them once and move on, if that. And I was kind of underwhelmed by the first Torchlight. So I was astounded at how enormously better this one was. Smart changes to things like identification, pets, enchantment, and so forth made the game tighter, much less tedious, and a lot more fun. The areas are (I think) randomized to an extent, but crucially they don't feel like it, having all the atmosphere and coherency of a carefully handcrafted experience. There's tons of enemy variety, and the classes have a lot of skills I really want to try along with a lovely three tier upgrade system, neither of which was true of the original. And of course, there's multiplayer, which I haven't been able to try yet but hope to soon when my friends get less busy with school and family.
Prototype 2:
I adored the first one. The second one's writing is even worse, if that's possible, but pretty much everything about the gameplay is better - movement, powers, missions, side missions, bosses.. and it looks significantly better, too.
