Stages
Bring back classic stages - like the living forest and the dead pool as well as the some of the most poplular stages form all of the MK games - This adds up to lots of stages about 30 +
No barriers whatsoever / Ringouts - If you can knock your opponent off the edge of a cliff stage for example before the finish him/her prompt then make it possible. But ringouts can be only done by performing a combo otherwise it would get annoying to your opponent to constantly get ring outs!
Multi-level stages - like in MK3 and also make it possible to knock your opponents though walls too and into shallow pools like ponds etc etc.I want a level where you fight knee deep in water so all the swooshing moves of you weapons would create great effects in the water.
Also have stages that are not level , for example you could be fighting on the slope of a mountain or on a beach covered in steep dunes (remember virtua fighter 3?) Or how about on a long and winding staircase?
All arenas have interactive backgrounds where you can pick up things like for example - your fighting in the PIT 6 (like the pit 1) level and all the corpses of fallen warriors lay scattered everywhere , well why not be able to pick up one of their weapons and use it? Another thing comes to mind here - multiple impalements but only on levels where more than one weapon is available to pick up. Another idea I came up with is a warriors tomb level and there are dozens of heavily armed statues from which you can pluck a multitude of different weapons.
You people remember the movie Gladiator? well remember when Ralf Moeller (Haken) the real big guy punched that black guy onto the wall spikes in the pit? how about something like that? gruesome! It wouldn't kill you just hurt you real bad.
Run Button - Hmmmmm .... yes or no? Vote on this I think , but I think I can safely say the run button is gone forever. What about triple tap forward for real quick forward dash?
