i hate settling one square from water unless i have a good reason (like extra food). i will first move my worker to the mountain north. this will give me a great view of what is around. i think that knowledge is worth losing a turn or two of work. my next decision will depend entirely on what i see.
the bonus doesn't tell me much other than a need to boost our early development, along with some military. not too revealing. maybe some early conflict.
the obstacle suggests that transporting units over water will become important. or this might indicate that our contacts will be far across the ocean and we should expect many attempts to fail. as an obstacle to tranporting units early in the game i don't see it having a wide impact. but, to limit the ability to make contacts would be a challenge for all victory types.
i'm guessing that we are isolated. although not as isolated as last month. maybe a small island, but with a rival or two this time. i don't think a domination will be realistic without better boat technology. we might have iron on our land mass, but i think we will have to fight for it.
i'll begin research on pottery. i'll attempt the republic slingshot, but i'm skeptical, no extra gold if we have no rivers or lakes.. if research seems slow i'll go straight for philosophy and then take maps free.
