Few weeks ago, I stumbled upon a YouTube channel named "Doom Wads" that uploads one video weekly (+ the month the week is set in) where they show a bit of gameplay from multiple WADs. They display the name of the WAD, the number of maps the WAD has, the author's name and the monster count. If you want to try new WADs, test fresh creations and keep yourself up to date with what's going on, I am confident you will find this channel interesting and useful. Moreover, because the NanoWADMo finishes less than 10 days ago, a lot of WADs were put in the video. First week of November. And here's the direct link to their channel.
