Somebody should take another crack at a Superman game, building off what worked in Returns. Especially since we've had stuff like Batman, Saints Row IV, Infamous, etc. all kinda show that superhero games don't have to be totally dumb.
Go to Apokolips and stuff, fight Doomsday to the death, rescue more kittens, etc.
Returns was almost a launch game, it was on Renderware ffs
And they wasted time doing PS2/Xbox versions (which still have the sweet flying even if it's ugly):
