I definitely don't think MKDC was a below average game, but definitely not the best MK. I'd say slightly above average. Thing is unlike the 3D games, MK team had no access to updates patches etc, plus look at COD lol it works for them so it can work for MK.
But I also have far more faith in WB over Midway when it comes to management etc so I'm not worried to be honest.
Besides, Injustice is vastly different then MK. I'm looking forward to MK 10
Fujin will be mine.
Hope they bring back 4 player tag, and perhaps more options such as an option to have 4 players online team up like a sports title and not just have two people online vs. another two online or one person controlling two guys, which should still be there just expand on that option.
