Yeah, i see the AIP auto increase as some sort of anti-stalemate tool.
Like, if you make no progress whatsoever for very long periods of time, the AI will eventually win.
Also thats the reason i have never tried spire civilian leaders. It just feels wrong to have even a theoretical capability to consistently decrease AIP over unlimited time.
Or do they go like "+1 AIP -2AIP", so eventually it just hits the floor and then the floor starts rising?
