One thing that I don't recommend is that you make cheap rip-offs of real wrestlers. Like I said earlier, the only thing you will get from a Stone Cold Alex Austin is being called a want-a-bee. If you're going to copy a real wrestler the at least admitt to it. I prefer original wrestlers but if you choose to go with an existing wrestler than please do a good job of playing their part.
E-Wrestling is an escape from reality as are all Fantasy RPG games(although they say that E-Wrestling borders on obsession for most). The choice between real and original is yours but just make sure you choose one that you will have fun with.
Whatever you do, make a wrestler that you can write RPs for. If you make a russian olympic champion that can't speak English, make sure they have a manager or valet that can do the talking for them.
