For me the top 5 games of 2012 were:
1. The Walking Dead
2. Tales of Graces F
3. Okami HD
4. Final Fantasy XIII-2
5. Lollipop Chainsaw
2012 game that I really want to play but just haven't gotten a chance to: Borderlands 2
2012 game that didn't disappoint me as much as it disappointed everyone else: RE6. With the exception of Chris' campaign, which is absolute torture to go through, I actually liked RE6 quite a bit, especially Leon's campaign, which I think nicely mixed the gameplay of RE4 with the atmosphere of RE1-CV. Jake's campaign was bearable once you realized it wasn't horror, but a strangely Metal Gear-esque tale. But Chris' campaign is just utter RE5-quality shit.
Disappointment of the year: Mass Effect 3...and not just because of the original ending. I didn't like that all of the ME2 characters were pretty much just afterthoughts. I mean, at the very least, couldn't Grunt have joined my party? He wasn't doing anything important throughout ME3. Then there were things like Anderson no longer being in charge of the council, no matter what you had previously decided, and me being on the outs with the Illusive Man, despite being on pretty much the same page as him at the end of ME2. I felt like too many things that happened throughout the series had no effect in ME3 and they ditched all the best characters (the ME2 ones) to appeal to ME1 fans. Not to mention, why are the only two new characters either 1) DLC or 2) big stupid meatheads.
2011 game I still haven't played that I will eventually: Uncharted 3
2011 game that I'm enjoying a great deal, having just bought it at the end of 2012: Dark Souls
Top 5 games I'm most anticipating for 2013: Metal Gear Rising, Ni No Kuni, Tales of Xillia, Beyond: Two Souls, and The Last of Us....provided, of course, that Final Fantasy Versus XIII and Last Guardian don't make 2013, which I would almost be willing to bet they won't, at least, in the West.
