Agreed. It is more evolutionary vs revolutionary, I think the best comparison I can come up with Gears 4. Gears was incredibly popular last gen but it was very much a time and place thing. Gears 4 is polished, same great gameplay yet the whole package feels somehow lesser than the individual parts. DOOM also was very much a time and place game. Yet, id somehow managed to make it fun and relevant today. They really deserve more praise for that.
It's definitely not revolutionary, but I'm not sure how that's even relevant to the discussion. Did someone claim that it was revolutionary somewhere in the proceedings? I think you're absolutely correct that
evolutionary is the best term to describe it, but I completely disagree with Gears 4 as a similar comparison.
Gears 4 came out 3 years after Judgement and added almost nothing to the formula aside from improved image quality and an excellent PC port. There's nothing evolutionary about it, it's the same game formula written against the most current graphics APIs. It's the safest sequel you could possibly design for an aging franchise. It's a great game, and I'm not denying that in the slightest, but it doesn't take any chances and therefore doesn't step out of the shadow of its formula/history in any meaningful way.
Doom 2016, on the other hand, came out 12 years after Doom 3, and it's vastly different from its predecessor in almost every way. It throws the formula of the previous game away completely and builds a new one that somehow manages to tap into the core of the genre-defining 2D Doom games of the 90s while also incorporating modern FPS design, and it even manages to go a step further by introducing innovative FPS gameplay mechanics in the form of the glory kill / forced aggression system. There's absolutely nothing safe about it, it goes in the opposite direction from the majority of popular/successful FPS games of the past half-decade, and the fact that it takes that leap and manages to stick the landing is an incredible achievement for id software and the Doom franchise in general.
Maybe it's impossible to see/feel the significance of Doom 2016 in the modern FPS scene without having lived/played though the history of the past 25 years of FPS gaming. It may be that those of us who think it's so amazing are just coming from a different cultural perspective, and if you grew up learning FPS gaming from COD / counter-strike then Doom 2016 might just seem like a high quality game that builds on some older arena shooter mechanics but doesn't do anything especially significant or exciting; those are both perfectly valid and equivalent reference points. All I can really do is express my own opinion for why I think it's an achievement worthy of GOTY in 2016, and that opinion is based on my reasoning that it is indeed
evolutionary, but in a market in which very few games (especially in the FPS genre) truly are.
