City (and Origins) is more like ZELDA with BATMAN imo
I think Origins has the best story and boss fights, City probably has the best gameplay overall, and Asylum has the best map/unlock path
I've never actually finished Knight, I was going to with my Batman playthrough for the blog but that stalled at the PS1 generation because of Batman and Robin which is both amazing in terms of being attempted (OPEN WORLD, DETECTIVE WORK, COMBAT WITH GADGETS, etc.) and amazingly awful in terms of execution (PRESSING A SHOULDER BUTTON TO SWAP BETWEEN CONTROL SETS FOR COMBAT, THE CITY REPEATING ALL THE BUILDINGS WHILE THE BATMOBILE DRIVING IS INSANE, etc.)
