Using shaders in-engine to handle pixelization/cel-shading also helps

I can attest the workflow is difficult. But I honestly believe that you can save time with procedural methods for as much as possible (terrain, textures, geometry etc). That does take away a bit from the handdrawn quality, but a worthy trade-off IMO. It's still a lot of work either way
