I think the beauty of mk9 was that it was a return to its roots and i think a lot of people would agree, including casual players. There's harmless presenation innovations like x-rays, different rendering, graphics etc. but then there's gameplay innovations which can be good or bad. I think they should put more of there innovative gameplay ideas into injustice and less into mk. Some gameplay innovation is cool, but not as "over the top" as injustice. I for one would be really down for a solid, tournament viable tag format where you'd have to kill both characters. So not like the tekken tag format. Oh yeah, it has to stay 2d too.
