I find alot of the crafting to be just well weird in 7dtd, for one, on the spiked club, those are in no way normal nails, those are like railway spikes, they are HUGE lol. In most games like these I often find it silly that you can mold metal into things with your bare hands. I know its in there for gameplay reasons but it still doesn't feel any less "WTF?" Then again i've played mods where even the most basic of crafting has to be done on some station, and i'd not wish that on the base game.
Needing schematics makes sense, what doesn't make any sense is how you can spend a point in a skill and then magically know how to make a car, or a motorcycle with 0 prior knowledge. I COULD see someoen cobbling a minibike together though, as it looks pretty simple. I prefer the old system where you needed books to learn how to make things, it made more sense that way. Ark Survival evolved kinda gets a pass, due to the engram system and how the implant is sorta like a internet terminal if you think of it, but there is nothing like that in 7dtd.
