I like to start on a large island of my own and not make contact until I am some way up the tech tree, preferably with an advantage.
In previous CIVs, I would generate the map, take a peek and discard until I found a good one.
I have done this 30+ times and there is always either an AI player on the same landmass, or is is too small. This despite only having 4 opponents on a huge map.
Does anyone else have similar playing style? How do yo choose your start options?
