I have an incomplete workflow for creating lowpoly models from highpoly models. here goes. 1. use zbrush to sculpt a high poly model 2.use the decimation master to make it into low poly in zbrush but then i get stuck with ugly topology that i doubt would be easy to rig and weight paint in blender to be used as game models…
I personally use Z Remesher with extensive use of curves to take it down a few levels, then I take them into Maya and manually finish it off in there. I haven't used an automatic topology tool that actually creates perfect topology, I'd rather do it by hand.
