My son's favorite game is hide 'n seek. Blaise's favorite part is finding the hiding spot, being found is secondary as he'll usually pop out before being found. "Clounting" is also a key feature as he enjoys doing this on a regular basis whether there is a game on or not. Acadia loves to tag along with either her brother or me, usually giving away the hiding spot if she is hiding or watching while she is supposed to be counting as the other hides.
We've recently expanded the territory to all three levels. I get left in my spot for long spells so I hide with a book now.
