I'd like a hybrid of modern day Universe and htcp career. Where you have a major focus on one guy and make all his decisions through in depth stories like in htcp, but you can still play the rest of the shows and Universe style cutscenes and storylines unfold that you have less creative control over.
Rather than replace Universe, keep it AND bring back a mode similar to RTWM from the 2011 game. You can freely roam around backstage and interact with other superstars/divas. Improve it with more consequences and longer/branching/varying stories, though.
It can be done, but maybe not in time for the next game.
A Universe that tracks rivalries, alliances and books over the years.
A career mode where you work your way up ranks to the main event of wrestlemania.
A hybrid could exist, but that would be very expansive require a lot of micromanagement. I think having the two seperate would be good. --- i5 2500 ~ ASRock Pro3 Gen3 ~ 2 x 4GB G.Skill Ripjaws X ~ EVGA GTX 560ti 448Core Classified Ultra 1280MB ~ Corsair 750W ~ Cooler Master HAF 922
