while the assets have optimized geometry and UV unwrap they are not game ready, meaning that the color/roughness/bump textures have not been baked to avoid texel density issues. future iterations will be gameready as soon as i figure out the right pipeline

short answer: no
long answer: well, since the generator generates all the geometry that will be baked into the lowpoly normal and curvature you can easily obtain 2+M poly per object if you enable all the displace steps in the generator, but as soon as you freeze the model and decimate it it's fine, just like you would optimize a sculpted model in a regular workflow
