Isn't this question really subjective? At any point in PS history, one franchise was better than the rest. I don't think you could actually king one particular franchise.
At one point God of War was the best. Uncharted is awesome now, but can it really be called the best? Hell, Wipeout was the best, way back when.
I just think it is really subjective, but I understand it is an opinion question anyway.
If pressed to answer, I would have to say God of War. IMHO
Im gonna have to say my personal favorite is the Ratchet and Clank series. Always loved it growing up and love it so much more in the HD Collection! Although wouldnt mind see the original 3 Crash games in HD lol. HD Polygons for the WIN!!
Without doubt Uncharted and God of War series yeah I mean BOTH....not the best PS Franchise but the best games ever made.There isn't a game to top Uncharted 2 and GoW 3...and if you look at the whole series you'll find nothing but pure epicness.And plus what UC dont have God has and what God dont have UC has.Jokes and exaggerated gore.I would pick MGS too but Kojima have been turning his back to us its been some time....also LBP the awesomeness of LBP cannot be described in a few words.
