To the (new) base game I have now also the (clear: new) Seafarers expansion of Settlers of Catan. Content provides the set a few new frame parts, ships in the 4-character primary colors, very many new water-fields and some commodity fields, including the new raw material here gold. Since the gold is not but as a real commodity in the game, the player who a raw material in the "Gold River" gets just selects any other commodity. The (new) Seafarers expansion ONLY works together with the (new) base game. Was the establishment of the base game but actually always the same, so there is a whole plethora of different construction variants, which are even more different, depending on whether you are playing with 3 or 4 players. This is also a great strength of this expansion, and therefore it is really worth the money - by the many varieties you have to play through only once - here comes as soon not be bored. The individual variations are in really great in a very large and very clear description. As with the new base game the pawns are in the new extension again of plastic - this time I find but even more beautiful than the old wooden figures - although I again recommend here too the Viking wood figures from the Catan Shop ... looks simple quality from. Two small criticisms, the expansion in my opinion. 1. There are no new construction cost cards (which are only in the extension of 5 + 6 players in it) - but here the cost of ships on some frame parts are printed. 2. The frame parts! In the new base game I have the frame perceived as clear advantage because they contribute uniquely to the durability of the playing field - that is, no matter how BUT ... they fit just fine together when the frame parts from the base game from above pushes into the frame parts of the Seafarers expansion - otherwise it hooks and unfortunately the parts go broke. Well - that is in the instructions very clearly in it - but I think here you could have the parts just something precisely fitting design. So be it - that does not detract from the gameplay. To build you need for the navigator but a little more time, as only for the settlers - and you have to schedule a pretty big play field - the table is there quite quickly. If the extensive construction is done only once, but it can go. Settlements and streets (or ships) set as usual - erwürfen commodities, act and build as usual. To the robber comes in this extension still a pirate ship, which can be used either at a 7. The number of victory points is also different (higher than in the base game), depending on which version one chooses to. The playing time is together with the construction of loose 90 minutes - but it is never boring. A very great extension that provides hours of fun. Strong buy recommendation!
