Finally a thread like this that I can actually post in.
1. Fable III - I'm really getting tired of the Fable series. It was kind of cute the first time, but now I just feel like I'm playing an RPG for five-year-olds. Lame
2. Kingdom Hearts: Birth by Sleep - The first good spin-off in the series and my favorite or second favorite Kingdom Hearts game. Recommended for fans
3. Ghost Trick: Phantom Detective - Fantastic game from the creator of Phoenix Wright. Likable characters and a great plot with plenty of twists and turns. PLAY IT PLAY IT PLAY IT
4. Oddworld: Munch's Oddysee - It has its moments, but it's disappointing overall and is nowhere near as good as the previous Oddworld games. Play Abe's Exoddus instead
5. 999: Nine Hours, Nine Persons, Nine Doors - Worth importing for its awesome story with a mind-blowing twist and people dying gruesomely. No but seriously, it's pretty awesome. Pretty awesome
6. Ever 17: The Out of Infinity - Written by the same person as the excellent 999. Has a great plot, but it starts out extreeemely slow and you have to play through the game four times (but from two different perspectives, at least) to see the true ending. Worth it in the end, though. For the patient
7. Mother 3 - Smaller in scope than Earthbound, but a lovely little game with a surprisingly strong and twisted plot. I never did get on with the musical battle system, though. Very good
8. Crusader of Centy - This was just boring. Boring
9. Dragon Age II - Some good moments buried under a mountain of reused locations. Not as good as the first game. A resounding meh
10. Jade Empire - The Asian setting looks great. I would have preferred it if there had been more actual role-playing, but the game is still pretty good overall, even if it wasn't BioWare at their strongest. Pretty good
11. Portal 2 - Just as good as the first game. Will hopefully get to check out the co-op with Peeps soon. As good as the first Portal
12. Ratchet & Clank: Size Matters - Decent, but not as good as the main games. Still better than Deadlocked, though. For fans of the series only
13. Secret Agent Clank - The same as above. More focused on minigames, which makes it feel a bit scattered, but it's decent overall. Decent
14. L.A. Noire - I'm still not sure of how I feel about this game. The gameplay could have been better as could the story, but there were some pretty cool moments too, I guess. ???
15. Commandos: Behind Enemy Lines - Super difficult and unforgiving, but once you get into the groove, it's surprisingly addictive. For the hardcore
16. Commandos: Beyond the Call of Duty - As hard as the most difficult levels in the original game, but just as fun except for That One Level. Takes place in more varied locations, too. For the even more hardcore
17. Commandos 2: Men of Courage - Introduces so many improvements/changes that it almost feels like a brand new series. I hated it at first, but eventually I got used to it and now I consider it the best game in the series. Awesome in every way
18. inFAMOUS 2 - Disappointing in the way that it's more Assassin's Creed: Brotherhood to Assassin's Creed 2 than Assassin's Creed 2 to Assassin's Creed, but still a good game. Slightly better than the first one
19. Enslaved: Odyssey to the West - The gameplay isn't the best, with its no-death platforming and button-mashing combat, but it's decent enough to make it worth going through to experience a game with really well-written characters and gorgeous vistas. The DLC is also worth checking out. Weak gameplay, great characters
20. Commandos 3: Destination Berlin Removes most of the stealth in favor of uncontrollable action. Was cobbled together to meet a deadline and was very obviously not finished when it was released. Trash
21. Daxter Better than Jak 2 and 3, though gets a little bit repetitive. Above average
22. Silent Hill: Origins - Plays like every other Silent Hill game, but it had been long enough since I'd played a game in the series for me to want exactly that. Silent Hill by the numbers
23. Radiant Historia - My favorite RPG of 2011. Ten years from now, when you're all talking about how much better The Elder Scrolls VII is than Skyrim, I will tell you how you missed out on a little-known timeless classic. RPG of the Year
24. Catherine - A good story with awful gameplay. Worth playing for the story, but the gameplay really gets in the way. Needed less gameplay
25. Willow (Arcade) - I don't usually play arcade games, but this plays just like an old platformer. Has amazing graphics considering when it was released. Pretty difficult, but that's not really an issue. Surprisingly good
26. Opoona - An awesome world with decent gameplay and a pretty terrible story. Definitely worth experiencing for the detailed world it presents, but don't expect to be blown away by the gameplay or story. Worth playing if you can find it cheap
27. Nier - Has a fantastic story once it gets going and it's worth playing through the (short) New Game+ just to get the full experience. The gameplay kind of lets it down, as does the obviously low budget, but it's still a game I'd recommend. Fantastic story
28. Xenoblade Chronicles - Sort of came out of nowhere, and then I ended up playing it for just over 150 hours. Really addictive and easily the best RPG on the Wii (not that there's much competition). You've all played this already
29. Deadly Premonition - Probably the weirdest game I played in 2011. Has a very intriguing Twin Peaks vibe and a town filled with quirky characters. Similarly to Twin Peaks, the plot kind of falls apart towards the end. The gameplay is terrible, but fortunately you spend more time interacting with the townspeople than shooting monsters. For fans of games that offer something unique
30. The Legend of Heroes: Trails in the Sky - 50-hour RPG on the PSP that plays very traditionally. Has a very well-written plot with good characters and is definitely worth playing. Needs more sales for the publisher to be able to afford translating the sequel, so feel free to buy more than one copy. Great traditional RPG
31. Batman: Arkham City - Feels a lot less focused than the first game and the plot is surprisingly badly written. Still manages to be a good game thanks to the gameplay. Play it with lowered expectations
32. Deus Ex: Human Revolution - Much better than I was initially expecting. Plays much closer to the first game than the sequel. Let down slightly by the horrid boss fights, but those are easy to look past when the rest of the game is so great. Classic Deus Ex
33. Uncharted 3: Drake's Deception - Disappointing plot with the characters we all know and love by now, and some absolutely amazing set pieces. Recommended
34. The Legend of Zelda: Skyward Sword - No comment necessary. Zelda
35. Corpse Party Fairly well-written downloadable PSP game about teenagers getting horribly slaughtered by ghosts. Can get annoying sometimes (why can't I skip text/why do I have to do things in just the right order/why won't they shut up?), but the plot makes up for most of it. Fun if you like gore
36. Super Mario 3D Land - The best handheld Super Mario game by a large margin. I'm still annoyed that they make you play through the entire game twice, though. But I forgive them
37. Stacking - The world is interesting - as is the idea behind the gameplay - but it's too basic and simple to be much fun. You can go back and try different solutions, but I just didn't see the point. Okay, but not much more than that
38. Where is my Heart? - A charming puzzle-platformer where you control three monsters as they try to collect floating hearts and exit the level. Kind of confusing and difficult and I got through the game more by luck than actually thinking about the puzzles. Charming, but the gameplay is merely okay
39. Bucky O'Hare - Starts out promising, but the character-switching mechanic is rarely needed and the game is JUST TOO HARD. You'd be hard-pressed to get through the game without abusing save states, and that's despite the game always letting you start over at the last checkpoint no matter how many times you die. Move past it and heal
40. To the Moon - Okay, so graphically it's pretty ugly, but if you can look past that you'll find a well-written and surprisingly touching story about the life of a man and the woman he loved. For the people who cry when they watch romantic comedies
Looks like it's been a pretty good year overall.
