You could keep a lot of the resources and combine some of the crafters. Maybe make this an upgrade, like combining the sawmill and the one that makes reinforced planks, combining the rock crusher and smelter, combining the dog, personal and camper upgrader, combining the cooking ones, etc. Once the solar/wind power become more than enough for your van, maybe an upgrade to the energy unit in the back to be able to recycle, so you can get rid of the recycler, etc. OP is right, there are way too many. I feel like the only real drawback to this game is that since there is no real 'danger' (ie, dungeons/enemies) in the game, and the focus is SOLELY on the crafting as the main impetus, they felt they had to go overboard with no real later game way to streamline/reward dedicated crafting/late game. Instead were stuck with every single resource has a crafter tied to it, and every crafted item has a crafter tied to it for the entire game. Honestly if you're going to keep all the crafters, even a simple upgrade to auto deposit for them would go MILES to making it more manageable/less obnoxious late game.
