I have been playing Civ 5 on difficulty 5 for a bunch of AI's, FFA style. I am having issues getting a good foot hold in my games. I feel as though the other players are expanding towards me first, cutting down on my space to grown. This wouldn't be so bad but it also appears as though I always start within 15 hexes of another player. I have tried playing with 'disable start bias' to give myself a better shot with the random placement but I am not having any luck.
How are these initial positions decided? Are there settings I can setup to give myself more space at the start of the game?
