I say it would help sales, and we would have back up incase MK2011 sucks/is ignored. I’m hoping it can be up there with SFIV/MVC3/KOF13/BB, ect, but with the PS2 era MK+DCU, people are going to be extra cautious, and scrutinize very hard. If this game isn’t near perfect, it’s gone. UMK3 is proven, still played, and waged a pretty good comeback. The main issue keeping UMK back right now is having to play on arcade, MAME or supergun, or other non-convenient apparatus.
There is the 360 version but it hasnt been available for years and you cant change the buttons, so meh.
Either that or a fixed Trilogy. By fixed, I mean slow the game down (Trilogy is faster than UMK3 by 33%), change the sounds sample rate and music to arcade quality, and have Shang able to morph into anyone, lastly change hitbox/character sizes/properties and proportions to UMK3 standards, with good online netcode, maybe some SP modes, and TRAINING MODE. I would vote for Trilogy because of some of the extra moves some people have, like Scorpion’s forward teleport, plus Raiden y0!
I think people would more easily buy the game, you get to try out MK2011, and if its good GREAT! But if not you still have a good/proven MK to play online.
