I think I get it. This event is more of a forum game. After results are derived, the participating creators (those who submitted the fighter-characters) have an option to publish the match material as a Tapas novel or adapt it as a Tapas comic.
I like it, but I am not participating. At least, I will not be a fighter creator. I expect to be crazy-busy beginning tomorrow with NaNoWriMo. (Furthermore, my aliens are notorious for sending others to fight for them.) I am going to be an adult here and resist the temptation to claim one of those seats on the judges' bench.
I look forward to seeing the results.
