Carcassonne will just became a spin off of the setlers of catan if this ocean thing came up...
lets' try to be original.
What makes carcassonne, Carcassonne? What differences are there between Carcassonne and Settlers of Catan? I don't really know SoC well enough (perhaps Whaleyland can correct me if I make any mistakes here) but this is what I think...
Tile placement -
Carcassonne: Strategically used as part of the player's turn
Settlers of Catan: Only carried out as part of the game to create the board
Oceans: Strategically used as part of the player's turn
Conclusion: Oceans = Carcassonne
Meeple placement -
Carcassonne: As part of the turn
Settlers of Catan: Resources needed to place meeples
Oceans: As part of the turn
Conclusion: Oceans = Carcassonne
Ocean tiles -
Carcassonne: None, but game has landscape features which can be scored
Settlers of Catan: Forms the border in the base game, Harbours (expansion) allows trading of goods, Fishing Grounds (expansion) gives additional resources
Ocean: Allow movement, has landscape features which can be scored
Conclusion: Oceans = Carcassonne
Resources -
Carcassonne: None, but trade goods (expansion) used to score points at the end of the game
Settlers of Catan: Does not give any points, but required to place meeples
Ocean: None
Conclusion: Oceans = Carcassonne
Dice -
Carcassonne: None
Settlers of Catan: Determines which tile produces resources
Ocean: None
Conclusion: Oceans = Carcassonne
I could go on. I tried looking for features where Ocean were more similar to Settlers than Carcassonne but fail to find any. I don't see how it could be a Settler's spin-off eventhough it retains the three basic Carcassonne concepts of (1) tile placement, (2) meeple placement, and (3) scoring completed features on tiles with meeples (even more so than say, the Catapult or Princess and Dragon!). I do agree that the 2 game have the same features (e.g. Rivers), but neither is a spin-off of each other just because they have features in common.
And this idea is original! It adds a landscape feature not previously available in Carcassonne or any of its expansions.
