What's the first thing you will be trying out when 0.13 goes live?

I will definitely try and be a "Lazy Bastard" and finish the game with max. 111 hand crafted items first. Made an early game dry run yesterday. Here are some tips for this achievement:

• Read this post from u/zane314 to see the minimum number of items that you have to handcraft
• Change crafting keybindings, so that you don't accidentally craft items manually out of habit. (I changed mine to ALT+Middle Mouse Button)
• Before your first assembler you can use the furnace as chest for coal, ore and stone mining

I really hope that most of the achievements work with peaceful mode on.

What are you going to do first?
