If Rocksteady can't make a good Superman, I don't know who can. Maybe just give to Avalanche and have them go wild like Just Cause style and expect an 80-90'ish game.
Also, if they can't make a good Superman game, how about you know some of the other many heroes like..ahem Green Arrow, The Question, Black Canary, The Flash, Blue Beetle, Animal Man, Swamp Thing, Constantine. ANYTHING
Cynical prediction, Rocksteady is going to have stopped making Batman games, pull out some flop Superman game because it just cannot be done properly(currently) and then Square-Enix comes in with an Avengers game that does well. Meanwhile us DC fans sitting here like DC fans. With some cancelled Suicide Squad game and Batman/Damian or whatever that really was.
Being a DC Comics fan, now I know what a Winnepeg fan feels like.
At least they cancelled the Marvel online MMO that was like Diablo so I can fan some solace that DC cancelled the DC Moba (that should have been like the Marvel game). (kidding, I liked Marvel Heroes)
I swear Comic business decisions play out like a comic book themselves, make no goddamn sense.
