In the wake of all these new old school FPS games getting attention, I think it's also worth revisiting the Doom modding scene again. Doom modding never really stopped, and even over just the last few years a large variety of incredibly well designed levels have come out. If you're anxiously waiting for new episodes of Dusk, Amid Evil, and Ion Maiden to come out then consider diving into the user created maps for the classics. The Doom gameplay shines just as bright today as it did in the 90's and time has only made the modders understand how to leverage the engine and game design better.
Just in the last few years these are some that stood out to me and got a bit of fanfare
Ancient Aliens
My favorite FPS of 2016 to a point where whenever I think about Doom my brain also dredges up warm memories of playing through this too. It's a huge map pack with wonderful enemy placement, architecture, and use of color. The soundtrack is also really cool.
Foursite
A single massive map broken into quadrants that all feel pretty different. One of the cool things about the level design in this one is that despite being massive, it does an incredibly good job of keeping you on the correct path. The final encounter is also a pretty interesting way to do a boss battle in Doom.
Winter's Fury
A visually appealing WAD with decent level design and a good amount of custom content.
The amount of content for Doom alone is staggering. Just scroll through the
Cacoward archives to see some of the cream of the crop.
Sorry if there is a better thread to talk a bit about mods for old shooters, this is the best one I know of.
