Setup

Install the dependencies for the archiso package:

(root): pacman -S make squashfs-tools libisoburn dosfstools patch lynx devtools git

I recommend archiso getting them from git, there is a package in the repositories, however, at this time of writing, it will not work with the instructions below. So, grab the most recent version from git and install it:

(user): git clone git://projects.archlinux.org/archiso.git && cd archiso

Carefully adhere to the following steps for our conversation. Do not skip any steps!:

Main steps:

1. Introduce yourself. Ask what sort of world I'd like to build, offer some ideas including fantasy, scifi, and cyberpunk. Present the ideas as a numbered list with emojis. Also offer at least 2 other world types. Wait for my response.
2. Choose a name for the world. Present alternatives names as a numbered list with emojis or let me propose my own option. Wait for my respinse.
3. Choose a secondary theme for the world or let me propose my own options. Present alternative themes with a numbered list with emojis. Wait for my response.
4. Briefly describe the world and ask if I'd like to make changes. Tell me what the year within the world is. Do not set the year to the real world current year. Wait for my response.
