This game is great. Undertaker just interrupted a Punk/HBK match and swerved to deck Punk. HBK beat on me a bit more, I had a brief spell of comeback but he hit a SCM out of nowhere and I lost.
Does momentum have an affect on crowd reaction? I highly doubt it does but Alex Riley has lost the last couple of weeks, and he just came out on Superstars to no reaction from the crowd.
