If you're bringing stuff I'd suggest you label it in some way, since it's easy for things to get lost or for there to be some disorganization, even at small gatherings like this. And by lost, I don't mean stolen. I literally mean lost, or at least taken but genuinely by accident (at least, I prefer to believe it's genuine). If there's like 20 controllers, it might be hard to remember exactly which ones are yours.
I won't be labeling my TV though, heh. If someone accidentally takes that...well, they'll have a hard time convincing me it was an accident.
