Settlers of Catan? Seafarers or Cities and Knights?

Question

Which is a better expansion, Seafarers or Cities and Knights?

Answer 1

Seafarers adds multiple islands, and allows you to build sea routes as well as roads. It adds a bit of variety to regular Settlers.

Cities and Knights is a BIG jump in complexity. You might want to have a look at the rules before you buy. Some people think it takes a simple game like Catan and makes it too complicated. Others LOVE it.
