Advantage- Being a huge mass of land createds
Easier transportation among neighbouring countries.
Able to have a more transitional climate allowing more different types of crops to be grown.
More cultural mixture.

Disadvantage- In real danger in times of wars cause surrounded by so many other countries and borders.
Diseases spread easily as there's no physical barrier.
Immigration and influence from other neighbouring countries.

This is all you, but i can give you some topics that you could try. if it rained when you want to do something outdoors, it 'limits' that human activity. maybe you want to do an experiment that goes throughout the whole year and you have to have above freezing the entire year. this 'limits' your activity. i thought of those just off of the top of my head. something that gets to me that might be getting to you is you are thinking too hard about what to do. think simply, and if it is too simple, then bump it up just a little bit.
