Oh yeah, I forgot, it's been a decade you used to literally just punch sheep and I vaguely recall when that update dropped. I recall eventually just looking stuff up, but a lot of it I figured out on my own first. Redstone is absolutely something that really needs an in game guide that the game completely lacks, nothing about it is intuitive at all, even if you know how digital logic works it behaves a little strangely.

I always played the game to build cool forts and castles so wool was definitely useful to me to make them look good.

zombies dropped feathers because the game didn't have chickens until sometime after 2012 (0.3?) and you needed them for arrows alphas are just like that. The Rust alpha was similarly nonsensical.

I always thought part of the appeal was just discovering the world and how it works, but it's so established at this point it's better to just have a guide in game.
