My wife and I play Agricola two or three times every Shabbat. She's better at it than I am, but I can still win about a third of the time.

We own Dominion, but we're not great fans of it. And I got her into board gaming first through Munchkin, then into Fluxx and Chrononauts (after which we never played Munchkin again), all of which I had played before, followed by Lost Cities (an excellent, light, two-player game) and then Agricola. She absolutely loves Agricola.
