I have to change Omnifactory a little. It's miscalibrated. I discovered that because Omnifactory replaces Forge and Foundry, it loses 11 base hammers (5 from Foundry base, 3 from Forge with resources, 3 from Foundry with resources).
The buildings that Omnifactory replaces add up to +290% production (+10% Oil Refinery, +15% Forge, +50% Steel Mill, +50% Advanced Quality Control, +65% Factory, +100% Nanofactory) and Omnifactory is only +10% above that.
The problem is that those 11 hammers from Forge/Foundry can have a gigantic ripple effect. I have a late Transhuman game going where a city nets +700% production over its base hammers: it has +230% from buildings (Forge, Factory, Steel Mill, Industrial Park, Transporter, Utility Fog, Deep Core Mine); +205% from power (Factory, Oil Refinery, Steel Mill, Advanced Quality Control, Nanofactory); +135% from resources (Creative Constructions and Deep Core Mine); +15% from civics (Superhuman and Protectionism offsetting Federation and Liberal); +20% land unit production (Military Base); and +125% military unit production (Secret Army Base, Arsenal, Recruiting Center, Military Academy, Ultimate Soldiers being offset by Industrial Park, Federation and Volunteer Army). So even with Omnifactory at 300%, it would lose 100 hammers per turn by building one.
So to properly calibrate Omnifactory, I'm going to raise its production bonus to +350% and its commerce to +50%. It's still not a gigantic bonus for a city that already has most of the production buildings, but it can be a big bonus for a newer city, although you can't rush with Post-Scarcity.
