Here are some things I would like:
1. Custom Music(Makes superstars more unique).
2. More Match types(3 Stages of Hell, Special Guest Ref, Inferno, Buried Alive, etc.)
3. Better Weapon Phsyics/Uses(Being Able to fold and unfold chairs, do backflips off chairs as a skill, actually landing on steps and reacting, basically like SVR 11-2K15.)
4. GM Mode(Obviously).
5. Better Injury system for Universe Mode(It takes a long time to injure someone, you should be able to do it in 1 match).
6. Season Mode(Obviously).
7. More Legends/Retro versions of characters(Legend Killer Randy, 99 Kane, 05-07 Batista, Terry Funk, etc.)
8. More Arena Presets(KOTR 01, Backlash 04, 05, 06, 09, Summerslam 03, 04-06, 07, etc.)
9. More Cutscenes from Universe or integration of Create a story(Basically we need more unique interactions between stars).
10. More Moves/OMG moments(Obviously).
Anything y'all would like to add or see?
