They need to put out a two disc set and call it MK Kollection or something... first disc has MK, MK II, MK3, UMK3(arcade), MK Trilogy(PSX, Saturn, PC), MK Trilogy(N64), and both mythologies games(maybe two discs for those games)... either sell this with that or seperatly a definitive MK Trilogy... Every version of Every Character and Every Stage from all the 2-D MK Games, and maybe one or two new ones...
Also improve on the fatality graphics, with a little effort they could make even the MK3 and up Characters have decapitations where the head spins and the body falls, I have seen fake animations that look good of this, also with a little more work all the other fatals could look ever so slightly better, of course give all of them combos and whatnot, give the bosses Fatalities and Endings that relate to MK3 storyline, sound cool? I think sell it for $20 and it would sell on the current systems.. later
