I think Sony should do some ESRB based collections. It wouldn't just have to be PS3 only. They could do it for PSP and PSN as well.

Like for PS3,

E= LittleBigPlanet and Ratchet and Clank Future: A Crack in Time

T= inFAMOUS and Uncharted 2

M= Metal Gear Solid 4: Guns of the Patriots and Demon's Souls

PSP,

E= Gran Turismo and LittleBigPlanet

T= Jak and Daxter: The Lost Frontier and Dissidia: Final Fantasy

M= Assassin's Creed: Bloodlines and GTA: Chinatown Wars

PSN,

E= Flower and PixelJunk Eden

T= Fat Princess and CellFactor

M= Punisher and something else that's rated M.

For the PSN M rating could be Siren: Blood Curse

I was hoping for a little more activity, but I guess I'm just so good that people don't need to comment.
