I've got three minor nitpicks:
- It's difficult to tell that only the Grand Oasis applies for the victory condition, at least without any explanation. Perhaps add some text to designate the difference?
- Ocean has the capacity to have 4 borders and a 7 bonus (not including the territory count). Suggest switching Marina down to a 1 to make it a more reasonable 6 bonus.
- Seascape has the possibility to get way out of hand compared to the other areas. Perhaps switch the foreign market bonus to +1 per 2?
