Derek,
I've given the demo a try and I came across a bug.  I had a fighter die in the arena so I put my next guy in for the following day's battle.  He went out and won, and was uninjured.  When I went to the roster management, all of his stats were zero except for intangibles.  If this is suppose to happen for whatever reason I don't think I got an indication as to why it did.  I tried to do another fight with him at zeros, and he lost (for obvious reasons  

 ) and his stats were still zero.  Just trying to help iron things out before release.
