I wrote a full, drawn-out diatribe of this game which you can read by clicking here
The developers of Injustice would have done better to simply copy MK vs. DCU and simply add more combat zones, characters and special moves. This game could have been awesome, but the developers T-rated it, and created another mindless kiddie game in the line of Dragon Ball Z and Smash Bros.
The characters are decent in number but they are poorly balanced and fighting feels horribly awkward. They take too long to auto-rotate when you jump over the other character and they all suffer balancing issues. The super moves are very difficult to dodge and become even more repetitive than the "X-Ray" moves in Mortal Kombat 9. In retrospect, the RAGE
system in MK vs. DCU wasn't so bad.
I was expecting so much more, but in the end, all I got was a fighting game that lacks the longevity of my Mortal Kombat titles.
