Supposedly this game is going to play more like No Mercy than anything, which is a good thing, because No Mercy is one of the best, if not THE best wrestling game to ever come out. Plus, they've got wrestlers that are also pretty big gamers giving them insight and suggestions too. AJ Styles and Christopher Daniels did most of the motion capture for the game, and both of them are game fans apparently, so I've got high hopes.
The gameplay features like countering and submissions run off of button combos rather than button mashing, which is a great move, IMO, because the past few SvR games have degraded into button mashing and nothing more. Pissed me off to no end.
There's some gameplay videos
here. Check 'em out, I think you'll be impressed.
