Just my own little compilation of interesting works of 2020. It's not exhaustive, and I haven't even played most of it, and I don't have any objective criteria or quality bar for what I consider interesting, and yes if [your wad] isn't in here then I probably found it uninteresting (speedmaps, my first wads, community projects with gimmick themes), or simply didn't see it yet, so don't take it as offense as I am not an authority and this list isn't definitive.    I started doing this because I noticed a huge uptick in community productivity in the last few years (new interest from bethesda-doom I guess), too much for me to even hope to keep up with playing, so I wanted a list to fall back on for when I'm in the old folks home. Also I have kinda grown to resent the Cacowards in a weird sort of way, as it has this side effect of nobody giving a shit about other wads from a given year - yes I'm aware we have periodic "underrated wad" threads but they're scattered and buried and disorganized with time, and yes this is just another forum thread that will suffer the same fate, although some day I intend to preserve the list in an old timey webpage.   Caveat: a lot of these could be works in progress, and a handful might not even be released, and some download links may be broken because people use weird file hosts, and I will edit in interesting wads as they come in / as I notice them.   2020 has been the busiest year for (interesting) pwads in all of the modding community's history, my evidence follows:
