When I come up with a scene in a game, and how I think is should play out, I tend to flick on a song that fits the current setting, and begin to act it out. If there is something that would signify a sword, staff, or any form of weapon, I tend to pick it up and use it as a surrogate for what the character is using.
The only reason I am asking this is because I find myself acting out a scene where the protag of a game I am working on storms a warehouse with her friend, all to stop some crazy mages and get her friend's sister back. I swing at the air, make gestures with my hand to simulate a spell being cast, and ready myself for a fight with the BBEG of the scene.
God I am a nerd, but it helps me figure things out on how a scene should play out. Does anybody else do this, or am I the only one? ^^;
