Maybe they should change the name of the contest to GW vs something other than RL because the rules specify that it can be from any other media, such as games, movies, tv, etc. It can be whatever you want it to. I don't have it word for word, but I've seen enough people complain about it and then be proven wrong, lol.
I agree with Souless, it has nothing to do with real life. And its already RL so why make it other wise? Its not that hard to place a character of a game in a other game...
