Regarding OOPMan's post:
Nyet! We already have a card game category. Right here. Now, about Koi-Koi -- what's the easiest way to get Hanafuda cards in SA? I wonder if any of the Generic Asian Supermarkets have them; I've never checked before.
ETA: I guess you can play with a normal deck, with four cards taken out.
ETA2: Nintendo makes them -- they started out as a card company!
