The four choices are:
TNA Impact 2- The first videogame was called TNA Impact and featured good qualities and bad qualities. TNA Impact 2 would imply a sequel, even if it isn't.
TNA Xplosion MMX- Named after the second show TNA relaunched this year. The MMX means 2010 which is what the videogame will likely be based around. The only negative is that the game would be named after a secondary show, which implies inferiority.
TNA Bound For Glory- Named after TNA's biggest show of the year much like WWE Wrestlemania was.
TNA Wrestling- No fancy name, stick to the company name.
Or if you don't like any names above, comment on what you would call it.
