I was simply saying "I have studied this **** and I'm telling you that 1+1=2". Yes it sounds patronizing, but that's because it is, your opinion faults into your lack of knowledge pretty hard just by cutting out this phrase here: "I disagree wholeheartedly. You're just not playing them. Rimworld, Divinity OS2, Disco Elysium, Factorio, Shadow Empire, Witcher 3, both Pillars of Eternity games, The Last Federation (edit: can't forget Cogmind and Kingdom Come!)- all were released in the past 10 years." - where you talk about your own tastes for games, without breaking down why they have better Design over older classics. I can do that, but I won't bother, I'm not the one reasoning against the funded opinion, you came to disagree, so that's your job not mine. (funniest part is that I've both played and liked most of the games in your list, that doesn't make them less **** when it comes to it's design depth)
G.D.D. = Game Design Document is a very specific thing, and your stance and what you are saying are incompatible with someone who has actually studied Game Design would say. When I've talked about reverse engineering games to re-write it's GDD is an exercise much like doing découpage technique with films, generally only those who studied can pull it off decently, and it always lacks the acid trip vision the game had before being finalized, it's a cleaner version of the original GDD generally, and it basically breaks down everything that can be seen (that's why it's hard to pull off), anyway, if you learn how to do that and actually try you'll notice massive dumbdowns within franchises, and when putting them side by side (Morrowind découpage GDD besides Witcher 3 découpage GDD), the difference in the resulting amount of pages can be seen from a mile away, don't even need to read it, witcher 3 would end up significantly shorter. Funny enough, though, is that again, by your list of games, most of them failed to deliver their original projects, all gotten "dumbed-down" during development.
