LARP'ing, no. I don't believe it would be entertaining enough for me...I just don't see the point, and I'd be too worried that the other people involved wouldn't take it seriously, or there'd be differences of opinion that would ruin it for everyone.
Now, a scripted play based on the story of Final Fantasy VI, that's a resounding yes.
Matter of fact, if I script and direct it, would anyone here act in it? I'm not kidding at all.
