Doomsday-Engine VS Obsidian

The go-to granddaddy of making it more modern is probably GZDoom. For some reason I don't remember, I didn't get on with it as well for "real" doom, only the big mods. (https://www.zdoom.org) My personal favorite that adds just enough graphical/audio enhancements without fundamentally altering the game, is Doomsday Engine (https://dengine.net/)

Doomsday Engine is the closest thing you will get to that .

A search for "GZDoom" on Steam will show some different indie games that are using the engine, there are a few interesting ones.

A cursory youtube search brought up this random video with a wide variety of examples: https://www.youtube.com/watch?v=UjnOdDzSxWs

There are also several versions of random level generators for Doom engine maps out there: https://obsidian-level-maker.github.io/

I can't remember the names but there are mods and games out there integrating the random level generators.

Of course the maps are still BSP and therefore somewhat constrained but the level of creativity in the mod community is pretty amazing.

Doom procedural level generator Obsidian has a mode to generate Chex Quest levels.

Doom 2, with HXRTC mod or DoomRL Arsenal and a megawad - look for a good one in CacoAwards or use the Obsidian map generator to generate one with exact paremeters you want for mindless shooting.

I know you say no FPS. But hear me out. Freedoom with gzdoom is argueably the most moddable game in existence. Not to mention, being the first game (Doom) to support mods, and the first commercial game to become open-source. There's a wealth of level editors and tools around it. Despite being from 1993, commercial games are still made with this engine.

Those who want random level generation in Doom should really try Obsidian.

I usually switch from one game to another every couple of months but i always return to modded Doom especially Project Brutality 3.0. You can even randomly generate levels for it with Obsidian (https://github.com/dashodanger/Obsidian) so you have endless content.
