I've never been into comic book characters, having rather grown up with the likes of Dragonball, Digimon and Pokemon but I like DC more than Marvel. The only half interesting Marvel character is Spider-Man so it's nice to see Insomniac making that. It fits in well with the kind of games they make, it looks like a fun title.
But again, I hope Sony never have their first party work on licensed shit. I'd much rather have original IP which they have complete control over, they are the reason I buy Playstation consoles and hope that does not change. Not that I think it will to be honest, Sony really don't seem to give two fucks about licensed games when it comes to their first parties.
As StuBurns said, a Superman game done right would be nice. I like the big boy DC characters like Flash, Batman, Wonder Woman etc a lot and Warner would do well to make games on them. Off Topic but what the fuck has happened to RockSteady?
