This is one of those labor of love games like Dwarf Fortress that probably will continue slowly updating until the devs die (which will be a little harder in this case since this is less of a one man show.) It has a lot of potential to do a lot of really interesting and weird stuff. It's always hard to review these because in a year the game could be different in ways that would make it much better or much worse than it is now, but I have been playing it a bunch lately so this is as good a time as any to say that the experimental branch that I am playing is pretty good.
While I understand some of the annoyance that this series sometimes provokes I think they are pretty fun and silly. The sprite work is really readable and the voice acting is pretty good. I disagree with Roberta's position that it's fun to spend months thinking about a puzzle, when I do that when I finally figure it out I usually feel mad. Which is why I played with my friend feeding me information from the hintbook. We felt like that was a good compromise between finding solutions ourselves and not pulling our hair out over a solution that we were missing pieces to complete.

This game is really the ultimate remake. Unlike most others it is recreating the feeling of playing the original rather than recreating the original. The 1993 Doom was a huge achievement, for the time, it kicked off First Person Shooters as a genera. Just recreating the 1993 Doom would not give people the same feeling in 2016 that playing Doom in 1993 did. Being that pivotal to the medium means that 23 years later a lot of stuff has iterated on that genera. Recreating the feeling of playing one of the first FPS games isn't just about improving the graphics and controls it requires them to create the synthesis of the original Doom and the entire genera that it spawned. Doom 2016 is as successful in that endeavor as I think it would be possible for it to be.
