Nice, i have Rock as a general manager for ECW. Ya, it can take a lot of time if you want to get really in depth. I wish that the matches could be chosen to simulate based on their stats, but it's whatever.
Right now i have Rhyno as my ECW Champion, Kurt Angle as my WHC on Smackdown, and John Cena as my WWE on Raw. I screwed up and made some stupid feuds in the beginning that didn't mesh well so my superstars got pissed off when i ended them after one month. Also, I'm building a Taker and Sting feud.
