Holy crap! It just hit me. Lol. The theory that many of you brought up, including
trufenix are saying somehow the involvement of a God that manipulates time is in the plot. For one, that we've seen The Joker, alive in the trailers, the whole "frozen in time" theme, and NRS haven't revealed how are characters able to fight Superman.
So, what hit me was, the game is called "Gods Among Us", alluding to multiple Gods. So, there has to be more, maybe even playable characters? I doubt it's just Superman that the game title is referring to as God.
I think everyone overlooked the whole title of the game
