It hasn't really changed. All in all it was a triump of Japanese gaming with games like Bayonetta, Vanquish, Super Mario Galaxy 2, KH: BBS, Gran Turismo 5, MGS: PW etc., imho very few western games were on their level or at all close to their quality.
1. Bayonetta / Super Mario Galaxy 2 / Fallout: New Vegas
Best from the East, best from the West. I won't even start trying to put these three in order.
2. Vanquish
I'm simply not the biggest fan of 3rd person shooters, which is probably the only reason why this isn't up there with Bayonetta etc. Vanquish IS the best of its genre, though, there's really no competition. Gears of Uncharted who?
3. Kingdom Hearts: Birth By Sleep
Starts a bit slow, but once you get some of those better skills/abilities, it's non-stop, explosive action.
4. Donkey Kong Country Returns
As I didn't mind the waggle-roll, this is up there as my favourite DKC with DKC2.
5. Metal Gear Solid: Peace Walker
A great portable MGS, don't really know what else to say.
6. Darksiders
I liked this a lot more than the past three Zelda games I've played (Twilight Princess, Phantom Hourglass & Spirit Tracks). People whine that it's just a copycat of different games, but I don't understand those complaints. There's enough personality there to make it a game of its own.
7. Ys: Oath in Felghana
So far, this is my favorite Ys game. Just all around fun, fast-paced & challenging action RPG.
8. No More Heroes 2
Improvement over the first in just about every meaningful way.
9. Just Cause 2
I wasn't at all interested in the first Just Cause. That's why Just Cause 2 was such a positive surprise. So fun, even if the main story isn't at all interesting (I haven't even finished it yet, just played around the island, trying to cause as much destruction as possible)
10. Nier
Kind of a hard job to place this. As an overall experience, it was one of the best of 2010 for me, but as far as gameplay goes, there are perhaps some games that would be better justified on a Top 10 2010 list... Anyways, a very different kind of game in every way and one of the most depressing gameworlds & stories in a long while.
The gap between 1st and 2nd in 2010 just reminds me how lame 2010 was overall; I couldn't even find 10 games to vote in.
That either shows how lacking your knowledge is of the games of 2010 and thus you didn't play many games like Vanquish, Bayonetta & SMG2, you only own a single platform or that your gaming tastes suck/are very limited. If you know of the existence of said games and own the platforms required to play them, then I'd have to go with the last option
