I wonder what people think about the possibility of making it such that low tech infantry divisions, low tech armor divisions, conventional engines, and maybe other pre-transnewtonian items didn't require trans-newtonian minerals to build.
It might also be nice to be able to construct conventional industry.
In playing an empire with very early technology and harsh mineral restrictions, it'd be nice to have that kind of thing as a viable option.
If there's a problem with balance, the cost of these items in terms or wealth or construction time could increase.
I recognize that this might cause coding problems because right now there's always a 1:1 ratio for something's cost in wealth and it's cost in TN materials.
