We love Dominion, a card/board game. You will probably only find it online, but we really enjoy its almost endless possibilities... Especially if you buy the expansion games over time. Carcassone is a lot of fun, too. No two games come out the same. And It's more intense to learn, but Settlers of Catan is very addicting over time. BTW, these three suggestions go from less complex to more complex in that order, IMO.
