I'm a relative newcomer to fighting games, but from the little bit I've played of the original Injustice, I've really enjoyed it. I'm very hyped for Injustice 2. What would be the best way to prepare for that game? Would it be more helpful to go back and learn how to play the original Injustice, or would it be better to pick up and study a game like MKX, assuming that Injustice 2 will have a similar engine/mechancis to MKX?
