i thinks so - i enjoy the challenge (trying either think up new
  games or scenerios - or simply trying to get into the spirit of
  his scenerios (and understanding the little detalis - that's the
  hardest part because they're VERY detailed sometimes - gotta
  keeps the 'facts' straight). There's loads of skills, physical,
  mental, intellectual, skills that you use while inventing or
  innovating games, or ...coming up with movie plots and acting
  them out. He comes up with these movies, come up with plot turns
  and twists, surprise endings, misleading characters - the bad
  guy who is bad through the whole movie but in the end, turns out
  to be the good guy, stuff like that. Being creative with "found"
  items. And the constant movement - creating, inventing, thinking
  and moving at the same time - I guarentee you use 100% of your
  brain at that time."
