For me personally for it to be the absolute best Final Fantasy Versus XIII has to release.

When was Metal Gear Solid 4 released? In 2008 or 2009?

Depends on how reviews for TLOU are

I have a really good feeling about 2013, but a lot of the games are not "my kind of games" really...
but let's see 2009, I already had MGS4, then Katamari, Demon's Souls, GoW Collection, Ninja Gaiden Sigma 2
it was a good year for jap fags like me :)

although with kingdom hearts this month, and versus POSSIBLY on the way, I'd say this year could easily dominate

2009 for me

Ratchet and Clank: ACiT (my favorite game of the gen and the last good Ratchet imo)

Uncharted 2 (liked 3 better but the highest rated PS3 exclusive of all time if I'm remembering right)

Killzone 2 (most people's favorite game in the series and one of the best FPS bosses ever)

Infamous (I really love this series and the first is my favorite as you discover your powers and gradually increase in strength)

Demon's Souls (didn't like it personally but people love it for the hardcore appeal which I didn't think was real because combat was easy but lack of checkpoints and terrible targeting system made it difficult)

Flower (not quite as good as Journey for me but damn is it touching)

GT6 could also come for PS3 this year, i'd say 2013 will be the best PS3 exclusive year.

Lol yeah we'll see if the Last Guardian is this year or not...but probably still not. Wasn't 2009 pretty stacked? I really don't remember and I'll be late for school if I go do research.

if GT6 is really coming this year on ps3 than hell yeah it's the best year for PS3 exclusives!!! alongside with Ascension,The Last of Us and Beyond.

If GT6 comes its this year.

Otherwise:
2011 and 2009 were the best.

2008 and 2010 were very good too. 2013 so far leans towards this.

2011 was weak.

2008 easily.

MGS4 by itself would be enough - but this was also the year we got LBP and Valkyria
