YES I would like a sequel for this after MK10 though.

I think Regime Superman should be his own character in it.

Also im sure they will drop certain characters (which is something I hate in fighting games) but I just really hope they don't drop Bane cause he is my favorite character in this.

Though I have the feeling Bane wont come back for Injustice 2 probably along with Killer Frost :(

You didn't have to make the roster thread if this is just a roster thread in of itself. But anyway, since Regime Superman still has his powers I think there's a chance for a sequel.

(Of course a sequel is determined more on sales than on story potential.)

I could see a new bunch of vigilantes breaking Superman out of jail. Maybe even someone on Batman's side may betray him. An outside influence from Darkseid or even Ra's Al Ghul could help stir things up. I see a lot of new characters in the sequel.
Such as;

-Ra's Al Ghul
-Darkseid
-The Red Hood(Jason Todd)
-Martian Manhunter
-Zaranna
-Scarecrow
-Braniac
-Swamp Thing
-Bizarro
-Poison Ivy
-Blue Beetle
-Dr. Fate
-Red Arrow
....and some of the current cast

I don't know if I would necessarily want a sequel. everything happened in an alternate reality. I would like to see them do a new story in the actual reality. Not sure who I would want as a bad guy or for a storyline, but I think that going with the imprisoned regime superman would be too similar of a story.

I also would like one after MK10.

I'd love it if they alternated every 2 years with MK and Injustice games.

As a newbie to the comic book world I've enjoyed learning about all the different comic book characters and their stories. I know there is PLENTY more material to make Injustice games for as long as possible and I'm cool with that!

As far as I'm concerned, Injustice could just be this stand alone game. The story was concluded, so it doesn't need a sequal. However, should they make a new story with an expanded roster, then I would welcome it.

However, right now I would want NRS to focus on the next MK, because I am DYING to know what will happen next in this alternative timeline. Oh, and I hope Reiko is in it. ^^
