... how about you sit down, watch a 100 minute long deep dive into a Doom "map" and tell me if it doesn't blow your mind. https://www.youtube.com/watch?v=5wAo54DHDY0

This may be interesting for people who are into creepy & surreal stories, liminal spaces and weird architecture and such. You don't really need to know or care about Doom at all to enjoy this. I don't know if I can say more without spoiling anything.

Very cool, thank you for the link. 100 minutes passed in no time.

Then, after watching the video, reading through o.g. thread is no less interesting:

I love stuff like that.

Neat video. Neat mod. Creepy, and well done. SO well done.

Very cool! Thank you very much for sharing.
Let me add this: John Romero plays MYHOUSE.WAD - YouTube

I love games that have a meta-level of puzzles and mysteries to it. Reminds me of "FEZ". When you "finish" the game, you still haven't seen or solved half of it. That's what "New Game Plus" is for then. Sadly, this game isn't available on GOG anymore, as it fell victim to some bullsht online controversy.
