Really hard to pick this six, theres so many great franchises that Sony owns. But I think I have the six most popular.

None of the above in my opinion. all overrated. well maybe twisted metal but we haven't had one on PS3 yet.

I think Team ICO games should be considered a franchise. They're set in the same universe, after all

I think Socom deserves a spot on that list if Syphon Filter and Twisted Metal are there

Uncharted.
Maybe Ratchet.

I don't really care of the others.

Gran Turismo pips Uncharted for me.

I love Uncharted to death and beyond, but Gran Turismo has been kicking ass for 3 generations now.

Uncharted is really stepping up as "the franchise" for playstation this gen. As for twisted metal, that series is more than dead. I would chose Gran Turismo as the best franchise right now but we haven't see a main game from this franchise in almost 5 years. Gran Turismo 5 is still a long way from now. Besides, I think Gran Turimso 5 is final game in the series.

OMG YOU FORGOT TO INCLUDE THIS AND THIS, BLAH BLAH BLAH!!!

I'm going to replicate these feelings for some of you.

Ratchet should be Sony's everyone-friendly mascot.

Think again.
