I have 2008, and its alright i guess. I get a bit of a kick out of creating my own wrestlers.
Whatever they do with the next installment, i hope they sort out the stupid loading screens for EVERYTHING. Everytime you do something you have to wait 30+ seconds while it loads. Also, the netplay is laggy as hell, that might be because i've only played with people on the other side of the planet.
Seriously, whats up with the auto matching crud? I'd much prefer to see a list of matches and be able to pick one without the game doing it for me... and failing badly.
