This is an awsome idea !
Everyone, ask your grandfathers and such for games they played as kids and get good descriptions of rules etc. No arkade games, nothing out of style, just good games, like the ones kids played in the old days. I would like to see horseshoe throwing and (beware of the lousy translation) \"throwing at the stick\" game my uncle told me about.
And Card games, with nice decks with pictures of gods and godesses on them. A picture of Link as the Joker is a must. Dice games, wich are simple to make. Chess, checkers, special card games like in might & magic 7.
I would hate a casino with flasy lights and slot machines. I dont think we should even call it a casino, but a gaming house, or the house of games or somethinh like that. Casino reminds me of Las Vegas.
