Injustice: Gods Among Us is hands down the best story in a fighting game I wasn't looking for. When I initially bought the game, I basically just wanted to match up fights with big-time DC villains and heroes because hey, fighting games are a fun way to pass time without needing a big time commitment to enjoy. What I got instead was an interesting story that was interesting enough to spawn several ongoing comic series and a second game (which I will definitely buy at some point!).
S.H. Figuarts made 4 figures of characters from their appearance: Superman, Batman, Harley Quinn and Joker. I like how each of these characters is a unique take in the game. In fact, the game has two versions of many of the characters: original versions and the alternate reality ones under Superman's One Earth regime, where he is High Councilor and is a pretty hardcore dictator/tyrant.
In this universe, Batman and many others are sent to an alternate reality (I won't tell you how, no spoilers!), and find themselves under Superman's regime. Some heroes (and villains) have allied themselves with Superman (who is looking kinda sickly!) while other heroes (and former villains?) have joined Batman's Insurgency group. This version of Batman is a bit more ruthless. He's got a bit more obvious armour plating to his suit, but it adds to the more unique world and takes on the characters. He's voiced by Kevin Conroy, so that makes most other things good in my books!
