Both panels are "normal" (considering now that chromo can't go to the 18+) but...
The theme is "Crossover" for the Panel (but that's optional) but only for the actual videos, and what we will be talking about and such. So we will be talking more about the Disney part of the games, and the newer games, ideas for newer games, etc.
So that means you can DO default or DO a crossover of some sorts if you want. So the steampunk CAN be used.
I kinda wanted, for the 18+, to be "default" or "crossover" as well, only cuz I think the costume will be recognizable, but still if i can't recognize your character, then we may have a problem (but i doubt there will be lol XD)
EDIT: BUT ONE THING! if you have something like TWEWY or Steampunk or something that isn't linked with the game, you have to tell me! Because I will try to find someone who will be willing to be your cosplay partner! So that way you're not left out and "stand alone" off ish. just let me know if that's okay with you guys!
What do you guys think? sound kinda fair? that way people can wear anything they like but still be a group?
