Personally I think it would be nice if we could build farmland that can be built upon by the actual city since most cities have farms supporting them and maybe the farms could produce tokens that would speed up factory production even if just by a small percentages such as 1.25% faster. Hope others like the idea.
I'm all for the variety of buildings and things you can build, but we've got the epic buildings that produce speed up tokens already, what would the difference be?
