Create Low Poly 3D models in blender, implement in a Unity factory game on a hex grid, and maybe output to mobile. Stick to quick development, low poly texturing with atlas, and assumed pre-knowledge of Blender and C# scripting to keep the course from being too long. Focus on efficient techniques and low resource/memory/video optimization. Authored by Stefan Persson (Imphenzia) or a combination of Hugo Cardoso (code monkey) and Grant Abbitt. Hugo has a youtube video summarizing his making of factory game.
