One thing I mentioned last time, on the ol' IWF...
Make EVERYTHING your wrestler does affect the status of your wrestler (face/tweener/heel). Not just your backstage promos, but the way you wrestle your matches. If your face, and you continuously wrestle slow, dull and boring matches, have the crowd's liking for you decrease. As it decreases, have the ability to push your character into a heel status, or face status, thus changing how the crowd reacts and your storylines/title shots etc. Also attacking other faces/heels should affect your status during matches. If you decide to attack your tag team partner, then have the computer (which will have MUCH better AI) help, and as they pin you, you can remain outside the ring (having their other partner not trying to stop you). These sorta things seem far fetched, but would make the game sooooo much better!
