A lot or a little?
Parents need to know that Catan is a single-player translation of the Settlers of Catan board game. The app has many tutorials, but the game may be easiest to play for those who have already played the board game. The interface is tricky in areas, particularly with a small screen. The game requires some understanding of economics and logic. A couple of weapons are pictured (an ax and a sword), but there's no violence in the game. A version called Catan HD is available for the iPad.
