it can be relatively simple to use if you don't want to get super detailed. That's why I could provide templates. It would do 3/4 of the base work for them, and all they need to is tweak it a bit for personal taste (body dimensions, coloration, hairstyle, etc.). But if you really want to, you can get really, really detailed. This, especially if you get creative in how to manipulate the various assets.I think it's a good idea to let players play fantasy races rather than forcing them to be stuck as humans. Whether you let them make their own race or just pick from a pool of options should be decided based on how much you value setting consistency versus player freedom, and how much you believe they would value it.
As for using hero forge, I can't really comment on that, never tried it before and I'm not sure how accessible for use (as in, simple versus complex) it is.
