I used eduke32 to blaze through DN3D once more on a boomer shooter kick a few years back. Which arguably never ended, as Doom and Quake mods make up most of my gaming time now.
If you havent played the Ashes 2063 mod series for DOOM I highly recommend it. https://www.moddb.com/mods/ashes-2063
Ive played a lot of excellent doom and quake mods...
* brutal doom, hell on earth starter pack
* blade of agony
* Hedon
* quake brutalist jams 1 to 3
* Arcane Dimensions
* alien armageddon (for duke3d)
but that one really stand out.
I was into playing and modding Doom back in the 90s and just a few months ago rediscovered the community - I am just blown away by the effort and creativity that is going into these source ports and the indie games people are building on top of them. That passion and spirit of sharing is peak Internet/open-source.
