There was a lot of technical challenges. Obviously, going from sprites to 3D characters, everything kind of feels differently. Suddenly, you can move the camera and you can move in 3D space. There was a feel of that's also where other fighting games were going. At about Mortal Kombat 3, Tekken and Virtua Fighter had come out, and those were 3D games. At first, those games fought on a 2-D plane, they started experimenting with moving in 3D.

I think that we spent so much time on the technology and we wanted to maintain the gameplay that people were so accustomed to and happy with, with combos and stuff like that, that, to me, Mortal Kombat 4 turned out to be a half 3D, half 2D game. You jump up and down, and you can move in a 3D space, but it was still trying to keep the whole Mortal Kombat I, II, and 3 high punch, low punch [dynamic]. We really didn't embrace 3D until we did Deadly Alliance, which was Mortal Kombat 5.
