Stunt Island was pretty good. However, there are more unusual games out there with reasonable budgets, like Death Stranding, The Talos Principle, The Outer Wilds, Portal and X4:Foundations. Even games involving shooting like Control or Alan Wake 2 are driven by unusual story telling.

We've come a long way in the past 30 years

Summing up the entire FPS genre as Doom-like is unfair and discredits you more than anything else. Heck, even Doom and Quake are wildly different.

FPS haven't been under the spotlights for a while, these days it's mostly MOBAs.

I do like Dusk (and most New Blood releases) if that's what you mean

Ultrakill is better than every DOOM campaign combined.

Miss falcon 3.0? Go with Falcon BMS. For any genre of games there is a modern remake and community these days.

I literally discovered a completely free and open source Total Annihilation/Supreme Commander remake last month which is great for nostalgia’s sake.
