The Last of Us better rise into the top 10 this year! Only 34 votes and it already got to the top 15, people placed it very high overall.
Uncharte 2 and MGS4 are going tl rise some positions too with the new games coming (also because I've played them while this year lists were already going, so they gonna rank mine this year).
I wouldn't be surprised if it stayed in the top 20, but I can't see it cracking the top 10. There's just so much competition.
If I had to guess I'd say The Last of Us will settle in around 17 or 18.
I don't think it will get lower, even more now that the game is coming always with the PS4 in USA, some guys here haven't played it yet, also new users will probably tend to know it more from now on.
The top 10 maybe it's too high, but Uncharted made it, TLOU can as well.
