Yeah, just rename the folders(like EWR2003) or whatever.
Also, if you start with TNA, always get a Styles/Daniels fued going, they do some GREAT matches.
Get a 1998 scenario, make your own promotion using the EWR Editor, and try to get them to the top!
There's so many good wrestlers you can sign, like Styles, Christopher Daniels, Kurt Angle, Jerry Lynn, ettc
Yeah, I know I really like that game.
What's fun is, get yourself a scenario from the late 90's, and pick WWF(or WcW) and battle against the other one.
