In terms of financials, it's a toss up between God of War, Gran Turismo, and Uncharted. But personal favorites taken into account. I'm going with Little Big Planet. Out of all the franchises Sony has, that one is the one you only get bored of if you have zero imagination.
I'm going to be one of the odd folks who goes with Mass Effect. I thought this series was very well developed (end of the third game notwithstanding). I was thrilled to see the series making a return at E3 this year! I actually cared about the characters and did all of the side stuff offered in the later games.
Syphon Filter. Hands down. God I miss that series. Sony has been "listening" to people lately. I hope they listened hard enough to let Sony Bend make a PS4 Syphon Filter.
Gran Turismo for me. I think it's their highest selling franchise. So I would think Sony themselves would consider it their top. MY personal top is Killzone though.
Definitely for playstation it has to be "Harvest Moon" I am pretty much fond of this game as it is kinda like a live simulation of managing a farm and at the same time making friends with villagers and marry girls in the village. It eats up a lot of my time and definitely loving it. You should check out this game
I've always loved Ratchet and Clank but it's been ages since I played it. I might buy the new one that's coming out possibly, it looks pretty good so far
