How is it fluff wise? Did they acknowledged the modern day setting more? What about mechanics. I dream of HtR 20, but it'll surely never happen...
Okay first off, there's a reason for the name of 20th Anniversary. Your Hunter the Reckoning will probably have some Kickstarter in like
2009 2019. V20 did come out in 2011, though W20 came out a year late, and M20 will be about two years late from its actual twenty.
So Vampire the Masquerade 20th Anniversary Edition, what is it? I have explained it many time on this sub-forum, but I love talking about it anyways.
So what 20A does is that it takes all this information from most of the past editions and splat books, while at the same time acting as setting agnostic as possible. The main Thirteen clans are there along with many of the bloodlines and most (so I have read) of the other discipline powers. The Bloodlines includes things like Salubri, the Cappadocians from Dark Ages, Gargoyles, Blood Brothers, True Brujah, Harbinger of Skulls, Baali, and more. All these different Clans and Bloodlines are given loving detail about what they are and little bits of fluff that relate to the meta of Masquerade.
The fluff the book itself goes by is what they call "Setting Agnostic". Basically, you an run Vampire in any point in the metaplot you feel comfortable with and run things that way. The book gives explicit nods in sideboxes to things like how Gangrel become an Independent and some of the Assamites come into Camarilla, how the Malks can have their Dementation replaced with Dominate unless set after "The Great Prank" (Though the main Clan page for them lists them with Dementation anyways).
The book tries to bring Vampire to the bare bone basic ideas of being a vampire in a world where mighty elders reign. Where the Camarilla wage secret wars with the Sabbat, and the Anarchs just want out.
Now to directly address the Modern Day setting, it doesn't.
V20 Companion is suppose to be the book that explains technology within the scope of a modern day world with smartphones, internet, and twitter. I couldn't tell you how well it does it, but it's a resource that could be of interest to look into. V20 Companion also covers things like "Titles" and "Prestation".
As of the now, there are books funded and coming out that sorta expand upon certain ideas and collect a bunch of others. Like all the Lore of Clans sound like it will take all of the clanbooks from the past and then compile and update them in one book.
Hunters Hunted II was released a while back. It is the update to the old Hunters Hunted, but I doubt it suppose to act as Hunter: The Reckoning 20th Anniversary edition.
All in all, I think it's a solid book. Since I haven't played older editions, I couldn't really say how its rules fair to the old, but I know its the usual roll dice pools against difficulty deal. Multiple Actions is handled in a way like so:
Say you are in a car and driving and are also shooting at a person in another car. You look at your dice pools for driving (Dexterity+Driving[+Celerity]) and shooting a gun (Dexterity+Firearms[+Celerity]). You then take the lower of the two and then split that dice pool between the two actions. I couldn't really bring up any other rules of note off the top of my head, but I say they're fine.
