How do you build a toolkit without any tools?
Might I remind you that the world was not made with tools included. There was no primordial toolbox that dropped out of the sky that all other tools owe their heritage to.
No need to remind me, because this doesn't really answer the question you're referencing.
Cobalt was closer to diffusing my point with an explanation of how tools are created. I guess the question is whether we really want to start users off with nothing but sticks and stones and make them build up until they create adequate tools they could use to cobble a chair together.
It's like the "advance tech level over time" argument, but in reverse. I could see it providing an additional survival challenge to hardcore players, but for the casual gamer it's unnecessary - and, let's be honest, the challenge provided is only briefly present in the very beginning, and then it's gone and you never have to worry about it again. Not enough substance.
Additionally, think of how this affects the early game. In Vanilla, you more or less have one year (give or take a few, depending on circumstances) to build a functioning, defensible fort before you start getting ambushes. When you throw in an obstacle like
requiring a tool to be created before you get early work done, this makes it harder to get the fort up and running within that window, meaning you'd likely also have to rebalance ambushes.
Now, somewhere I saw a suggestion for a portable toolkit that allows the user to build a construction on the spot it was designated (it's in one of the threads Footkerchief listed). This is an idea I could get behind. It's a small investment to create a reasonably sized persistent reward, and I don't think it's enough to make the game too easy.
I suppose I should post a quick disclaimer. I often play Devil's Advocate in these suggestions as a means to encourage sound arguments for why they should be included. I do hope it doesn't come off as trolling because that isn't the intent!
