The Shadowlands were originally intended to be a fully playable zone in World of Warcraft, designed for high-level play. The idea was that as deceased characters made their way back to their corpses, they'd see high-level players battling creeps in the area, which would inspire lower level players to increase their character level so they could experience the zone for themselves.
Keep raising the level cap with no changes to the leveling experience up to that point. This leads to ever-lengthening leveling ramps that make it extremely difficult for new players to get to current content. That's because each expansion adds another several dozen hours to how long it takes to get from the start to being able to play with friends in the endgame. (Final Fantasy XIV has this problem to some degree, even though it's nowhere near as old as WoW.)
World of Warcraft: Shadowlands marks the eighth major expansion pack for the storied MMO. Judging from a half-hour playing it at BlizzCon this year, it seems like a natural evolution of modern WoW that will run alongside the very-different WoW Classic experience for the foreseeable future. That said, the biggest change wasn't part of my hands-on demo—but don't worry, that won't stop me from geeking out about it in extreme detail.
It's hard to get a sense of an entire World of Warcraft expansion from 30 minutes of play. In my short demo, I recreated my main (a Beast Mastery Hunter) and played through the introductory quests from the Bastion zone, a heaven-like plane from Azeroth's afterlife. The minute-to-minute gameplay very much followed the formula of modern WoW questing, with a variety of tasks like challenging specific enemies to duels, helping craft things in timed minigames, and of course, killing 10 rats (well, not rats, but they might as well be).
But it gets even more interesting when you look at how it will work for alts (second or later characters made by existing players). New characters made by existing players will have the option of leveling up the old way in all the same old zones from the start. But they will also be able to go through the new-player starting experience if that's what players prefer.
As always, though, Blizzard really delivered on the art front. Bastion is striking, with big, beautiful skies, banners realistically waving in the wind, and fascinating characters, like a humanoid, owl-like race that inhabits the zone. Blizzard artists told me that they plan to support RTX raytracing, as well as new kinds of real-time lighting, in the expansion. I'm surprised by how good modern WoW looks on a high-end PC these days, given that it originally came out in 2004, and it looks like that work will continue.
Explore the Realm of the Dead: for the first time ever in World of Warcraft, players will cross into the Shadowlands and experience the wonders and horrors of the afterlife across five new zones—the gleaming fields of Bastion, the scarred battlefields of Maldraxxus, the eternal twilight of Ardenweald, the opulent keeps of Revendreth, and the horrific Maw.
