Are video game Characters underestimated in the battle forums?

Ive been on this site for months and i love it but i always see people bashing video game characters in the battle forums. Well known characters that i think would be a great match for many marvel and dc heroes/villains. For example Kratos Alex Mercer The Assassin creed characters and so forth losing to heroes by the majority of comments that really surprise me. Most people use feats and so forth. I figure its just that most of the people havent played the games through all the way. In the end i think a lot of video game characters are underestimated in the battles boards. Lemme know your opinions please.
