Well this time i didnt start nextdoor to them toltayans, and now they are at war with everyone they have met, mega evil empire just kicked in i guess. I had MEE disabled for awhile now for testing purposes.
By checking the scores seems that those Toltayans are n trouble now, their score has been in free fall past 5 or 10 rounds - it was over 3M, now its about 2M.
I guess i was too worried too soon
Some 4 or 5 games before this, i kept having toltayans as my first (and only) neighbor, blocking my way out to the rest of the galaxy, but seems they are only nasty enemy when its early in game, for me anyway.
As long as i can keep my corner of the galaxy clean & safe (about 25-30 systems), i should not have any problems from the AIs - this time - my empire creates 800k research and 150k intel points per turn, round 73 ..
