So I've been a fan of 40K for a while and lately have started taking free Codex's and trying to make them look more appealing as well as include the rules in one spot, since a lot of free codex's use out of date rules that are only contained in one other pdf, which uses rules contained in another out of date book (see the Kroot Mercenaries list for this).
Unfortunately I'm running out of free Codex's to do this to, so I was curious what homebrew Codex's could be recommended. I don't play a lot of homebrew armies so I do not know which ones are balanced, which ones are fun, or even which ones are popular.
I do this in my free time when I'm bored and this also helps me get better at making them. Attached is an example of my work (normally the page isn't this full, it's just that HQ in particular had a lot of options).
