For starters….
Multiplayer – Read that while Batman’s experienced, he isn’t the veteran he is in the other two games. So it’d be nice to have a partner help him out.
Use of vehicles – I’d always hoped the Batmobile would be a playable vehicle during a mission. Like having to catch guys who were speeding away in a truck or something. Or the plane, which I read is in the game. Wish I had use of the plane in Arkham City during those timed missions. Especially the Victor Zsasz ones.
Being in the Bat Cave – It’s Batman’s home. A true Batman game should allow the player to have to be there to do some detective work on the Bat-CPU. And to change his Bat-costume if he wants to look differently on his next time out on the streets.
Villains to fight:
Scarface
Red Hood – just always wanted to see him in a game after that Under The Red Hood movie.
Man-Bat – he’d be a cool villian.
Firefly
Clock King – he’d make a good sub-villain for timed side missions
Riddler – Time to actually see him in person, face to face.
I’m aware of the villains who were in the previous games that are gonna appear like Joker, Bane, Scarecrow, Quinn, etc. I hope Joker doesn’t talk because no one could top Mark Hamill as The Joker. I wanna have one last boss fight with Scarecrow, Croc, Bane, and the others.
Want music composed by Fish and Arundel.
That’s it for now. Will add more later.
