The venerable (and fun!) board game translation, Catan, gets a new expansion, available for $X.XX as an in-app purchase.
The Cities and Knights expansion introduces various new gameplay mechanics that add even more variety to Catan. Invest new trade goods in city improvements to build one of the three metropolises of Catan – but beware of the barbarians attracted by Catan’s new wealth! You’ll need your best knights to fend them off! C&K contains a short campaign and 7 challenging maps.
