One day they need to make a Batman game with an older Batman. We've got Arkham Asylum and Arkham City which show us a seasoned Batman in the prime of his career.
We've got Arkham Origins now which still has Batman in his prime but I thought they did a good job at making him raw, having him make mistakes like when he choked that thug out while interrogating him and when he failed to tie up the Electrocutioner.
Now we need a Batman game where in the beginning, he is retired. Maybe around 55-years-old like in TDKReturns. Maybe he retired because Superman decided to clean up Gotham, so now instead of a dark dingy city we get "Gothopolis" (Gotham/Metropolis...get it?) but of course Lex Luthor shoots Superman with a kryptonite gun and Vandal Savage leads a private army to lock down Gotham. Now, Batman must return.
This should make up about 20% of the game with side missions and all.
Bruce has heart problems which make him not the Batman he once was, so he creates the Batman Beyond suit and fights crime with that.
Then, he confronts Vandal Savage and the two fight, but Batman has a heart attack and is forced to pick a gun up off the floor and SHOOT VANDAL SAVAGE!! Of course Bruce knows he is immortal so he didn't really kill him -he just needed to get away- but then we get the scene in the batcave where Bruce hangs up the cape and cowl for good and turns the caves lights off. Fade to black.
TWENTY YEARS LATER
Introduce Terry McGinnis. Maybe have a portion of the game with him walking home from school and catching a purse snatcher, maybe saving Bruce Wayne from a group of thugs, just to get used to how he fights and introduce Wayne to Terry. Then Terry would return home later and find his dad has been killed.
From then on, he would find Bruce, get the suit, and the rest of the game would be a detective mission to solve his dads murder.
Anybody who watched Batman Beyond knows that Derek Powers was responsible. Perhaps this will show him turning into Blight (I hate that name).
You could have boss battles with gangsters using venom-slappers. You could fight Inque, Shriek, Rewire, Jokerz, Curaré and the Society of Assassins....honestly Terry's rogues gallery is pretty big. Like Arkham Origins, this would be Terry meeting these villains for the first time.
I think this sounds really cool and I hope they do it.
ARKHAM BEYOND - THE LEGACY CONTINUES!
