/vr/ - Retro Games

I know this would probably be more suited for /agdg/, but I wanted to run it by you bros first in case anything just happened to know something.

Assuming DECK ever comes through and makes it it probably won't, we'll probably have a viable method to make retro sprite-based FPSes. There's Harmony and Action Doom 2, both being full-fledged games, but since they're built in ZDoom they can't really officially be called "games".
In the meantime, though, what other methods are there? I've created a pretty popular ZDoom mod that I'd like to expand out into its own thing as a full-fledged indie game, kind of like what DoomRL is doing (except it's not a Doom mod I guess), but the big thing that baffles me is just how...clunky all of the existing options seem to be.

Unity clearly isn't designed for FPSes.
The Unreal engine is used fucking everywhere, and is more relevant to 3D shit than 2D.
Pie in the Sky HAHAHAHAHAHAHAHAHAHAHA
Game Maker might be interesting but every FPS I've seen done in it has been pathetic at best.
RetroBlazer and Nexuiz were built off the Dark Places engine and can handle 2D through hackery, but being based off the open-source Quake code won't that cause licensing issues?

Any viable options out there for an aspiring modder looking to make a full-fledged retro sprite-based indie shooter?

But will you actually be making anything beyond what's "planned"?
