That just sounds like 2K.
What exactly would you be able to create/do in a 3D version of Fire Pro that you can't do in the WWE games? All of the creation and match options are basically there. Fire Pro is appealing because it's a completely different experience to the WWE games. In 2K, you can already create belts, shows, arenas, performers, logos, etc. 2K basically is the 3D version of Fire Pro...and people still like Fire Pro (because it's not that). If you make Fire Pro the same as the 2K games, then you just cease to have an alternative.
I specifically said graphics only. I personally dont like the sprite/2d graphical scheme. I literally said graphics only. You mean to tell me by going 3D you cant have a different game than 2K? Yeah, no.
