I am a player who would much rather plough the land with the building troops and found cities everywhere than worry about diplomacy, peace and war.

Is there possibly a mod that allows you to play without AI opponents, i.e. without other factions?
The aliens and the other 4 victory options would be enough for me. I would just like to play without annoying neighbours who declare war on me every 15 turns.

First of all: I have mastered the game and can also win it on the Apollo difficulty level. So you don't have to explain to me how to deal with them. I just want to spare myself the trouble and manage a planet in peace...
