KnightFighter: I'm not fooling myself. I have been part of turn based sites for many years now, as I'm sure you probably have too. I have also been playing card games practically my whole life, and am quite aware of the limitations. Yes, a huge majority of card games would not work. (At least not in a "satisfying" way)
My point was that no one needs to "wake up". Fencer has already said a card game is coming.
There is already at least one turn based site that successfully has card games, as well.
