This is where I am at too. Even at $10, I was unable to pull the trigger due to not being a fan of having games I can't finish. Reading how the level design was a chore was the larger drawback to me as well.
I wish they rebooted this in the manner of homage to the OG, like how DOOM is, or at least RtCW with the paranormal elements, even possibly having some "same universe" blend with DOOM since that is paranormal as well.
Such as the acts of Hitler with the paranormal in the OG and Return, were early research linked/kicking off into what was expanded on with DOOM (clearly set in the future).
I mean shit, we borrowed the rocket research (V2) for NASA IRL, so why not have that paranormal link between the two franchises in a canon manner. Then DOOM Guy can still be the decedent of BJ.
