Mortal Kombat's far too bloody for me. However, my older sister is a huge fan of the series. For a side by side fighter (as opposed to a ring like structure, like Soul Calibur and the PS2 MKs), I think it'd work great. However, I think a ring fighter would put the 3D to better use - something like Broken Destiny on the PSP in 3D would look fantastic. Circling around the environments in 3D would be great. As for controls, MK is a 6 button fighter as well, so the 3DS would be fine for it. The bottom screen could be put to use like SSFIV3DE's with panels, or maybe just for fatalities. Put in StreetPass/Wifi interruption battles like in SSFIV3DE, a single, solid mini game (I actually liked the mini games. MK Chess looked cool, and the racing game was fun. It just needed tighter controls), and some kind of StreetPass simulation system, and boom, I think it'll work well. For the SP simulation battles.....instead of using figurines or trophies, maybe if they let you build a custom character, and then put that character away for SP simulation battles. When you walk by someone, that one character will do battle with someone elses, and it'll save a replay. That way, you can look at the fight afterwards.
