It's great, but if your group is used to something like Catan, it's much more time consuming. Great at ending friendships, however.

If you want to play in one sitting, in-person you need 6 or 7 players for a good 6+ hours...So basically it's a game for college students (I played it a lot at uni).

As an adult you can try to online versions where you only do one move per x(usually 24) hours. The games last weeks but you can play remotely at your leisure.
