This is a very difficult thing to define, because they are paying for each game they play in, paying to be at the event, and the TOs are aware of anyone who preregged being in multiple games. TOs are more than willing to accommodate the Chris Gs and Sonic Foxes because they excel and draw viewers and possibly competition. This is part of he business aspect. There can only be so much time it takes before a player gets back, but there needs to be a rule established where first come first serve, no other tournament can interrupt and steal a player out of the line up. So say Fox is playing DOA, and he is called for SC, that's a lock. We can't sneak in and get him for Injustice. I've seen that shit happen to us and it sucks. As long as we are aware a player is in the building, playing another game, it's VERY hard to DQ them and you have to go to the person in charge of the entire event before you do because they are the ones who will be held responsible. It's bad if Injustice DQs Chris G for being in the Grand Finals of Marvel.
