I play blackjack, and love getting dealt Aces, since they can count as one or eleven!
I see, my fiance deals blackjack, it seems like a difficult game
I guess if you counted cards to alter your play it would be difficult, but it's not hard for an average player.
Is it mainly about luck, do you play against the dealer or other players?
You play against the dealer, not the other people at the table.  I think it's a game of skill, though.
