If MK8 wasn't MKvsDC, then DC and WB wouldn't have gotten to work with the MK Team and got to see how talented they were. If that didn't happen then there is a good chance that the game we are getting next month could have never come to exist. A lot of good things came because of MKvsDC. Also don't forget they got to learn a lot of lessons with the platforms and engines while making that game, making MK9 become the solid game that is has become.
