I’m using daz3d with blender from blender download makehuman system assets. Blender assets can be used in Daz3d. There is many how to video’s out there. Here’s a tip make your city/background before you write your story or you may have a lot of rewriting your script/story. Best thing to do is check each program assets to see which would work for you the best. Just be careful making your game it could become a money pit if you are having to buy program/assets/backgrounds/audio files. Well hope that was helpful. Take Care and good luck 😉
