limit Star Bases in suns
Yes I love building multi SB's in the suns grav well, but the AI has a hard time taking out 1 SB let alone 2, and once u have 3 or 4 it can't do anything.
3 nearly fully upgrades TEC SB's destroyed the combined forces of 2 Advent allied AI's last game. (inc dozen of cap's and stacks of their long rang missile ships). I actually panicked and brought my fleet in to assist, but by the time I got there the battle was over.
I have stopped building multi SB's now as it's not fair on the AI.
