The best game of 2010, hands down. Why can't all games be this good?
2. Red Dead RedemptionRed Dead Redemptionhttps://giantbomb.com/wiki/Games/Red_Dead_RedemptionOpens wiki page
Grand Theft Horse. But better than any GTA game, without doubt. The entry into Mexico goes down as my gaming moment of 2010.

I only got this for Xmas, so it *just* sneaks into the list. A fantastic achievement, better than 2, and almost GotY. But its irritatingly long load times (Despite a HDD install), and ME2's sheer brilliance, just nudge it down.

Janky. As. Hell. But still awesome.

Short, sweet, genius. More of these, please Mr Publishers.

Yes, I know it was Zelda in a big suit of armour, but I really enjoyed it. And I finished it on HARD.

XBox graphics, but next gen story. Thoroughly enjoyable.

Speed speed speed speed.

I bought the game, borrowed a PS3 to play it on, and then gave the game back with the machine. Totally worth it. Finished it in 2 nights, hooked from beginning to end, despite the nagging gameplay janks. Press X for Jason.
