Changes would obviously have to be made. You can't make a stealth game starring Superman. You can make a perfectly good game with him, though. There are tons of ways to do so. Use his large rogues gallery that includes enemies that can use his weaknesses against him, and actually delve in to the universe some.
You could do Legion stuff, you could do what Superman Returns did and make parts of the game about protecting Metropolis and the people within it.
You could even do sections where he's Clark Kent tracking down a supervillain that can evade his senses by using investigative work in a similar way to the crime scene parts in the Arkham games.
Of course. I mean, there's tons of heroes that could use the Arkham system with some tweaks. For "herald" level heroes though? You'd have to change the mechanics big time. I just think it's worth doing, especially if we get Justice League or Avengers games out of it.
Or just release more MUA/MH/DCUO type games. They balanced it well enough.
Glad you enjoyed it more that way, but getting 100% on Arkham Knight did very little to redeem its already existing problems for me, so I still say **** no to them doing another Batman game at this time.
I feel like they'd learn from their mistakes. I'm of the opinion that Arkham Knight was the worst of the Arkham games (including Origins) though it had the second best story. The overreliance on the batmobile and the disservice to Deathstroke are what killed it for me more than anything.
I'm just not sure what they'd do. They already gave Bane, Ra's Al Ghul, Joker, and Scarecrow their own awesome and finished stories (Joker dead, Bane and Scarecrow are a shell of who they used to be, Ra's died but he could come back I suppose since his corpse was taken). The only villain Batman has left that can carry a story is Riddler IMO. Unfortunately, that would leave the other big villains out of the game and leave us with the B-D list. Plus, Bruce is now outed as Batman now so I'm not sure how he'd continue to fund his crusading.
I feel like Superman has more possibilities at this point. Plus, Brainiac is my favorite Supes villain so starting the series off with him would be pretty exiting.
The combat, especially aerially, is going to be the hard part. I heard mention that his flight would be involved, so my guess is that his speed would be too, which would allow them to bring over at least some aspects of the Arkham combat too.
