I can thoroughly second that recommendation for Decino's playthroughs. I don't think I'd personally enjoy playing through things like Going Down[0] or Eviternity but I really enjoyed watching him play through them while I was cooking dinner or half-working :) His "analysis" videos are also excellent, he's really good at talking through and presenting some interesting Doom engine curiosities and quirks. They'll be interesting for many HNers: https://www.youtube.com/watch?v=o78DzBJ4Rv8&list=PLYZp53E4M0t_8HmPlV4m04vGKUcJIQc53 https://www.youtube.com/watch?v=o78DzBJ4Rv8&list=PLYZp53E4M0...

  I watched a few of their playthroughs and I sometimes see things in maps that appear impossible in the original Doom engine. I'm often wondering if those are some clever trick in the map or if the map is running on some newer variant of the Doom engine that has features not available in the original. Sometimes they do explain it in the video, like in that one map that had a randomly chosen math question the player had to answer by pushing a button. I wish they would do that more often though.

    Yeah there are definitely things that rely on a specific version of a given doom port. If you ever hear Decino (or others) talk about something in a level being specific to "GZDoom", they mean exactly this - some functionality wouldn't work in the original Doom engine, often some simple scripting

    “Silent teleport” is a original Doom trick often used to good effect - Doom isn’t true 3D, but one floor ‘above’ another can be achieved by invisibly jumping between areas horizontally displaced in the underlying map.

      I've never seen that in any custom Doom maps, but it was a common thing to see in Duke Nukem 3D and other Build Engine games (Blood, Ion Fury et al)

        The original Doom engine does not have it, but a very popular port called Boom added many new things and one of them was a silent teleporter, as in, walk over a line and get teleported to the same position in a line of the same length somewhere else. It can be used to make many interesting effects. I used them in... I don't want to say every single one of my maps, but 90% for sure. The one caveat is that they don't render what's on the other side, so you have to recreate the geometry manually and monsters will suddenly disappear or appear. Vertical, floor-to-ceiling portals are a bit more new. I think only the Eternity Engine and GZDoom support those. They also support portals that render the other side, monsters and everything. Edit: Oh, I forgot that you can get portal-like behavior in the Vanilla engine by hacking the BSP tree used for rendering, see https://doomwiki.org/wiki/Linguortal https://doomwiki.org/wiki/Linguortal and also here for a more visual demonstration: https://www.doomworld.com/vb/thread/74354 https://www.doomworld.com/vb/thread/74354

Decino is amazingly prolific. I'm not sure I know of another creator that has the depth and breadth into a specific category of gameplay as him. Over the pandemic there were some creators that started going deep into playing various Super Mario spins, but Decino is almost on anther level. He has been churning out Doom play throughs regularly for the last 3 years, and he really goes into the theory and code of how Doom works in his yellow background videos. Very impressive YouTube channel.
