dudalb: I know that sometimes bizarre rights issues pop up,but hopefully we will get these ID games in the near future.
It would be great to see these games here but as far as Heretic & Hexen 1 on GOG are concerned, like Doom 1-2 they are best played today in a high quality source-port like
GZDoom where all you need are the 3x IWAD files (HERETIC.WAD, HEXEN.WAD and HEXDD.WAD), at which point there's zero practical difference between copying the same data files from a Specially Packaged GOG version vs original disc / Steam release. Hopefully GOG can get these games here for those who've never owned them, but for those who still have the discs / another version, if you want to play them DRM-Free & client-less you already can without waiting another 25 years "just in case" the rights holders eventually get their act together, and for which playing them via DOSBox (how GOG would package them as they do Doom 1-2) complete with 35fps frame-rate cap, no mouselook, 320x240 resolution, etc, isn't always the best option...
