Would be something cool to look forward to with in-game gold. Just sittin here, smoking a pipe, dreaming up things...
I hope not, I really, really, hope not.
Poker would be utterly out of place in a game like this. And the setting, cards are made of card, have you ever seen anything in TES made of card?
I could see dice based games of chance (Like the Witcher's poker) fitting in or dominoes oddly enough, but nothing like cards.
