Which game should I play next?
If you have never played it before, you should definitely play Metal Gear Solid 3. IMHO it's the pinnacle of the series, it has some great mechanics that I have not seen in another game, and the core story between Naked Snake and Boss is absolutely brilliant (and the rest of the story can be pretty bananas but hey it's an MGS game). Plus its a prequel so you don't have to play any of the other MGS games to find out what's going on.
I've beaten MGS3 in one sitting three times, and I'm not someone who speeds through that game (it generally takes about 12-14 hours for me). But if you haven't played it by now I have to assume your attachment to the series now isn't anything like what mine was back then, pre-clusterfuck 4, so I wouldn't necessarily recommend it.
The first two Uncharted games are pretty damn cool - the second more than the first - but both have such terrible final levels that if you've played them both, if I were you I'd either move on to Uncharted 3 where they got everything just right or let the fact that you forgot most of those two games shield you from those dreadful endings.
For similar reasons, I didn't vote Last of Us. If you've played it and beaten it, move on. It'll always be there for you when you really need it (however, if you really want to go back to that world, by all means.)
Have no thoughts on Assassin's Creed IV, both I and II got incredibly dull halfway through their campaigns and from what I've seen in Quick Looks since the combat is still a paltry facsimile of Arkham combat, so I'd pass.
Final Fantasy XIII-2 is based on Final Fantasy XIII, which I only played the demo of and honestly have no interest in sinking the time into. Battle system seems intriguing but I think I left my JRPG marathoning days back in grade school when I had more time and less interest in liquor.
So, my vote is Grand Theft Auto IV. Crazy, I know! GTA V is out there, doing everything GTA IV does way better, plus the Online that finally gives people like me who don't know how to create their own fun outside of rampages something to do in that world for as long as I may choose. But GTA IV is a wonderful little creature, Liberty City is a truly hilarious place and the first third of GTA IV is truly a masterwork even if it gets a little messy afterwards. The graphics engine hasn't held up well (I finally played Episodes from Liberty City over the summer in anticipation for GTA V) but nearly all the characters are memorable, the missions are great (seriously, why does everyone always bag on GTA's missions?) and even after all this time spent with V, I still think GTA IV had the most immersive inner-city gun battles I've ever been party to. Walking through apartment buildings with a shotgun in that game just immediately doubles your heart rate, and for some reason playing GTA V no-hud just doesn't have the same adrenaline rush it did in Liberty City's enclosed spaces.
