Have you looked at the V6 playtest? If so, what do you think?
I have, and I am Not A Fan.
It's less about the specifics and more about the broad general approach.
Let me explain: I liked v5. Not as much as I like v20, but I think that's an unfair comparison. v20 was essentially the fourth iteration on its framework, right? where they had been able to refine the vampire 1e mechanics over three more editions to get the very fine tuned end result that is v20, because they had the benefit of a lot of hindsight after seeing it in play. And, of course, material from 1e is still basically compatible with v20, as is material from the other wod gamelines up until that point.
So. v5 came out, and v5 is very much a break from this iterative process that lead from 1e to v20, right? It creates a new game engine with new structures. It's got some really interesting ideas, but it's also got some very heavy flaws. So, I like v5 a lot, but unlike v20 there's a lot of things in it that I think are obvious fixes in a new edition. So for a long time, my stance on v5 was "I look forward to the better version of this we'll get in sixth edition."
And sixth edition comes along, and I have been really excited to see how they'll build on the foundations v5 laid down, and...
instead, no, they're starting over from scratch all over again, with a system that's even more divergent from either v20 and v5 than those are from each other.
I am upset about the v6 previews less for what they are, and more for what they are not; they are not the iteration on v5 I have wanted.
But, okay, here's the thing. People talk about the lore changes v5 made, and I think that they massively overstate how much v5 changed the setting. The changes to the setting in v5 take basically 3 forms:
moving the timeline forward from the end-point at the end of Revised, and the result of events that happened in that extra timeline. The formation of the Hecata is the result of an in-fiction event that unified the various scatted Cappadocian bloodlines (and also the Nagaraja are here). The tremere's changed clan weakness is the result of the Vienna chantry getting blown up. Et cetera.
Consolidating things together. Most notably, with disciplines. Things like Serpentis being a form of Protean, Dementation being folded into Dominate, and so on. The one that makes people most angry is folding Obtenebration and Necromancy together into Oblivion, but I actually think this makes sense; both are overtly magical disciplines drawing power entropic from the dark umbra and the spaces below it (if they had included Daimonion in v5, it would also be a variation on Oblivion, because it likewise draws power from Spiritually Below). Likewise, rolling various bloodlines back into their parent clans and so on.
Expanding on things hinted at in earlier editions of v5 but not fully explored. A good example of this is Thin Bloods; there had always been talk about the very high generations being semi-mortal and having the ability to use the blood to create new vampiric powers; the thin-bloods in v5 are simply building on that.
So v5 is not actually that divergent in its setting from earlier editions; no more than the divergence between 1e and 2e, say. It exists in a continuity with them. Yes, the Giovanni have a new discipline spread now; this is the result of an in-setting event that shifted the nature of the Giovanni, similar to events like The Great Prank for clan malkavian or the Giovanni themselves becoming a clan and shifting away from the Cappadocian disciplines. Yes, vicissitude is part of protean now, but the vicissitude powers are still there.
Where I like v5, I like it because it's ultimately an extension of 1e-v20, just with new mechanics. The mechanics could use a new edition to tighten them up, but when I run a v20 game in the modern day, I use v5 fluff.
As much as the mechanics were new, the setting was still an iteration. Translating from 1e-v20 into v5 and visa versa took a little effort, but was doable.
Now. From what I've seen of v6, this is far less the case. From the - admittedly limited - preview materials, it seems like they're much more willing to play fast and loose with the setting and to change things for the sake of changing them.
I could list a bunch of specific changes they've made that seem incredibly stupid (eg: why do they imply that koldunism and chimerstry are the same discipline?) but that's not the point. No one change is the problem here, and some of their mechanical ideas seem good. Not all of them - doing an anti-wassail if your humanity goes too high is Fucking Stupid - but some of them could be interesting.
No, my problem is that they seem to be changing a lot of things extremely recklessly, meaning that I don't think v6 will exist as a continuiation of 1e-v5; the basic facts of the setting will be too distorted with little in character justification, meaning its setting is not compatible with the setting described in the earlier editions.
And maybe if I was more inclined to view it charitably, I'd be more open minded about the sledgehammer being taken through the setting. But on a fundamental level, I was never inclined to view it that charitably, because by being what it is, it actively shuts of the possibility of an improved v5, which is something I'd been actively looking forward to for a while. Conclusively shutting down that possibility gave it a much higher bar to clear for me to like it, and it didn't clear that bar.
Like in the vamp community, you see this talking point where because the vamp playerbase is split between v20 and v5, they had no option they could pick that would please everybody, which isn't untrue. But I like v20 AND v5, and building on either of those would have made me happy, and instead they've picked the secret third option which makes nobody happy.
and nobody IS happy, really. The only people I've seen who seem to have positive thoughts about it are people who, frankly, don't play World of Darkness and do play stuff like Daggerheart.
