Ah, all that explains it. See, I wasn't using loopholes to get an ultra-high score and all that, I was attempting to get the AI to challenge me (sent in a nice sized uni-paragraph about it to MM

. I used finite resources, I had max AIs, both neutral and normal, with highest difficulty and highest bonus. So, building all planets with Monolith Facility IIIs was not a possibility, especially since it seems that resources max out at 3mT per planet... And I never liked BaseShips/StarBases except for a few things... like warp duty on a very busy hub system, or put over a big planet if I don't feel like building my WeaponPlatform suite... or when I capture them
I'll have to try for the ultra-high score game sometime.
