[quote name='Punk_Raven']Aki didn't want to do another wrestling game....
Only reason that I can think of of why they haven't made one ( atleast not brought to the North America? ) in a while.[/QUOTE]
Aki just hasn't had many wrestling game projects to work on - they've done anything asked of them, including the Def Jam wrestling games (and developed the PSP port of Def Jam 2), and the Ultimate Muscle games, but they just haven't had a chance to do stuff for another group. Apparently, they didn't want to work with THQ again due to THQ being hard to deal with, which seems reasonable given that they had very little time to complete No Mercy, and still had to develop VPW 2 alongside it. They may not have been happy with the final product, which did turn out to be glitchy, suffered from slowdown, and lost some features, even though it's considered by many (myself included) to be the finest U.S. 3D wrestling game ever.
