Rising Tide
Rising Tide expansion adds some cool new features. You can build cities in the ocean and later move them. You can modify diplomatic relationships. However, this version still has bugs iin it. My first game crashed after turn 340. I have it saved it but no matter how many times I try to relaunch, it fatally craches between turn 340 and 341. This needs to be fixed.
