I posted this over on BGG as well, but thought I might get more hits here.

I realise that a lot of times people ask the hypothetical question about which game to bring to a deserted island. In our case we live on a small sail boat, we're literally going to do the deserted island thing... We have intrigue, sea side and prosperity at the moment. I'm quite keen on adding the remaining expansions.

So given that we have limited space and we're potentially only taking one game to the deserted island, what makes this game so great and so replay-able?

Obviously I can do the math and see the logic, I thought it would be fun to get some opinions...
