A compilation of every Doom WAD/Mod that were either featured on the Cacowards (the Doom modding community's awards) or were listed on the Top 100 WADs of All Time (basically retroactive Cacowards for WADs released between 1994 and 2003). The 2018 "Missed Cacowards" are also included.

If you want to get into mods for classic Doom, or want to find something you haven't played already, this is a great starter pack!
