The link attached to this post contains all Cacoaward winners from 2004 to 2020. I have seen a few others on Archive.org such as this one but they seem more focused on backing up everything.

I am wondering if there is a collection of total conversion mods like Total Chaos, Trench Foot, and Ashes 2063 for example.

I imagine there are a lot of best Doom WAD lists out there but it would be nice to not have to go through the effort of downloading them individually.
