Settlers of Catan is one of the all time great Euro games, the one that started the Euro craze and one of the first games to make serious inroads on Epic Duels time.  We don’t play it much anymore in part because this is one of those games that Cagey dominates online, Roman also plays it pretty competitively so it’s beyond the casual game at this point.  We’ve played the expansion, Seafarers, Cities and Knights, the whole nine yards, but the best game is probably the original.
