It does when the question is "When was the 2024 book written?"Level Up is just as much a different edition than the 2024 game will be, albeit in very, very different ways.
The math of the game is not the only thing that matters.
@CleverNickName is trying to downplay the playtest because they think and keep saying essentially that the books are already all done... and thus implying the playtest isn't real and is merely just for show. Well... they are "correct" in that most of the game (including all the baseline mechanics) ARE in fact already written, because the baseline game is still going to be using everything that was designed for the 2014 books and ain't being changed. Level Up was the same way-- which is why it was designed and marketed to be an expansion of the 2014 5E, with the entire foundation of the game and how it works already handed to Morrus on a platter and thus everyone who buys it will know pretty much how the game plays except for all the added bells and whistles (like it is for every single 3rd Party designer and company.)
The stuff that is getting changed for 2024 is all the same top-level bells and whistles stuff... little rules issues being cleaned up, underwritten things from 2014 getting deeper dives, balance issues being brought better into line. And none of that stuff is or needs to be completely written right now. All that surface-level stuff can be tweaked, adjusted, and shined up real pretty for all the players who submit their surveys about what they like and don't like because doing so isn't a big deal. "You all really want the 'Use An Object' Action added back into the Thief's 'Cunning Action?' Really? Uh... okay... fine. We think the Action doesn't work very well and think there's probably a better design there... but if you all REALLY want it... we can put it back in if it means that much to you. It ain't hard to do and ain't gonna affect anything."
And the people who think there's no point in testing or submitting surveys? They say that because they know that the baseline game is staying just how it is, and since they don't like it or are bored with it or want it changed greater than what they know WotC intends to do... there's no reason for them to bother. The playtest is all lipstick on a pig for all of them. Which is fine.
