Like my other thread "What is your favorite weapon?" Now I ask what is your favorite prop? If you don't have one, maybe just one you use a lot. My favorite is probably the vending machine. Good strength and not too expensive. My favorite design one though is the ball pit. (It isn't that good of a prop though)
Props are momentary irrelevant aspects of the game. If one was truly enlightened, he'd learn to play and win the round without utilizing one prop the entire time which I have done. This is why I am God, perhaps one day I'll share my knowledge with all of you
