So i just got into deity, and I'm having some degree of success, winning a few games, but it seems 80% of the games i play end up with me attempting to expand, but the AI quickly surrounds me and chokes me off. Then they all declare war on me and start landing units all over the place. I have no problem fending off the attacks, but i cant expand, and any attempt of me trying to get a settler to an island usually ends with the boat being sunk by all the AI ships in my waters.
This eventually leads onto me falling behind in all victories, and me placing next to last.
I basically make a settler whenever a city reaches 4 population.
Should i be making more? Should i be rushing them? Or is there a particular way of going about expanding that will make things easier for me.
Any help is appreciated.
