A pretty idiotic concept that has hit or miss results. I think some battles like Dan vs Hercule and Raiden Vs Wolverine were decent. Others like Snake vs Sam Fisher and Iron Man vs Luthor were pretty stupid. The analysis of each character can be hit or miss, sometimes they put the fighters in scenarios that favor one fighter{like batman vs Cap} and sometimes it can be utter bullshit{Sonic vs Mario}. Personally though, I don't care one way or another because I love all the nerd rage it creates.
