Giant Death Bots for zero gold?

[Troy Bruckner]

In one of my cities I was able to build 2 Giant Death Bots a turn for zero gold. Playing as Mansa Musa and I had a military Academy.

Yup! Modifiers to unit purchase cost are additive rather than multiplicative, meaning that certain combinations of cards, city states, and notably Mansa Musa's abilities can bring that down to zero in the late game. Units will still (without other modifiers) have maintenance costs, and require resources, but yeah, a properly-built late-game Mali can build a devastating army for free at the moment.

Yes Sugaba and Encampment with Military Academy, suzerain of Ngazargamu, and democracy apparently give you 100% discount on buying units so if you've got enough uranium you could field numerous GDRs.

Along with two Nobel Prize rewards that gave me a uranium every turn for every University I built 20 of them and still had uranium capped. I have to say it's broken just like pillaging.
