Fact is, this is a PlayStation celebration game, it should and needs to have games/franchises/characters/universes that are important to PlayStation. Currently, Big Daddy, Raiden, Kat, Nariko, Emmet, Fat Princess and new Dante aren't important to PlayStation so they shouldn't be in this game, or at least shouldn't be in this game before characters that are actually important to PS. That's something I'm extremely disppointed in.
Some games that are important to PlayStation that aren't in this game yet are: (and remember it's just some, not all)
Metal Gear Solid (Snake, not Raiden)
Battle Arena Toshinden
Grand Theft Auto
And of course, many, may more.
