not sure if serious but i would also say FFXIII

nothing comes close to RDR .

Donkey Kong Country Returns.

God of War 3

Red Dead Redemption. Nothing comes close. What a game.

Ah 2010, my favorite year for games this generation, actually of all time to be honest. I loved God of War III, Red Dead Redemption, Mass Effect 2, Alan Wake, Castlevania: Lords of Shadow, God of War: Ghost of Sparta and I really liked Bioshock 2, Heavy Rain, Limbo and Splinter Cell: Conviction. Also I liked Bayonetta, Darksiders, Dante's Inferno, Halo: Reach & Enslaved.

I'm going to with God of War III, a.k.a. the most perfect hack n' slash game ever made. It's a once in a generation game. I don't think anything else in the genre will ever come close to its 93% average score and 6+ million sales, unless God of War IV is a return to form and then some which I'm unsure about after the bitterly disappointing GoW: Ascension (still a good game though).

The ranking (so far):

1 Red Dead Redemption
2 God of War III
3 Super Mario Galaxy 2
4 Mass Effect 2
5 Heavy Rain
6 Halo: Reach
7 Metal Gear Solid: Peace Walker
8 Pokemon HeartGold/SoulSilver
9 Assassin's Creed: Brotherhood
10 Starcraft II: Wings of Liberty

I had a typo in the poll XD

Mass Effect 2. An honourable mention goes to Red Dead Redemption.

I can't decide between four games: Assassin's Creed Brotherhood, Red Dead Redemption and God of War III all qualify for Game of the Year. Brotherhood is bashed for being AC2.5, but damn what a fun game.

The fourth GOTY candidate is Final Fantasy XIII, one of the best of the series.
