I'm not a fan of multiple ways to craft the same thing, it clutters up the recipe menu and why? If unbalanced then add more bones, not make some weird way to achieve the same thing. Then its like hey how do you get glue and the noob gets 2 different answers. Confusing.
I'm swimming in glue but I kill every animal I see with my sniper build. I changed it to 1 bone for 1 glue in 17.1 so you guys will have twice the glue as before, it should be plenty.
I'm getting the impression that when you played Skyrim or any of the other Elderscroll games, you didn't spend all that much time in doing alchemy or the like areas?
This isn't a dig at you in any way, because everyone has different things they like and excel at, and this just doesn't seem like an area you are really into.
If the above is even remotely close: I don't think you should focus on the recipe area of the game. You obviously have a strong artistic and creative flair, and I think you and the game would be better served if you embraced it more.
Maybe, turn your focus on decorating biomes, mess with their distributions, amounts and so on, help beatify your world in other ways, instead of needing to make new textures/UV's and so on.
You made a quest line mod in the past for one of the elderscoll games, so why not start putting together a couple/few kick-ass quest chains we can do? It doesn't always need to be just about getting the loot, but could also start expanding the lore of the world you are putting together, or telling a survivor story that failed/succeeded etc,.
You could also take a page out of the scroll games, and have the recipe system just not tell you how to make everything but only the basic stuff, and let the players figure it out with the alternate methods.
Edit: Can't be complicated to a noob if they don't need to know about it, or need it, to complete the game to a satisfactory point
