I played quite a few hours of the game, both alone and together with a couple of friends.
One day, after a couple of weeks or something, I learned about a crafting wiki that told you how to craft different items.
At the time, at least for me, it was not clear how you figure out what items you can craft and what items need to be combined in what patterns to craft those new items.
So for me, that crafting wiki became quite essential.
Maybe other people were figuring out how to craft things by trial and error? Or maybe there was something in the game that told them how to craft specific things?
