WB has been actively trying to develop an open world Superman game since 2013

So much mismanagement by WB. One game was cancelled because WB wanted the devs to use the Arkham engine, which wouldn't work with Superman's flight.

The Kandor idea is EXACTLY what I’ve been thinking they should start off with, just like how the Arkham games started off with Batman trapped in Arkham Asylum. It’s the perfect excuse for why Superman doesn’t have all his abilities at the start and can gain them over time. Either Kandor or the Phantom Zone would be the perfect settings for a Superman game.

Of course they could always just use this guy:

His power levels are perfect for a game, but I don’t have much hope for that. The next gen is going to see a huge leap in CPU and GPU processing power along with SSD’s severely cutting down on loading. I hope next gen finally brings us another Superman game.

Well, at least they've been trying...

I guess it's an improvement over the feeling off "they just don't care" that we've had for the past several years.
