There are a few things I’ve wondered about Worldsoul Saga. Who exactly wrote the core story. For a cohesive comparison of “story” think of the original Lord of the Rings movies, a saga in essence, that got written and then delivered by the same few people (look at the mess of Episodes 7, 8 and 9 of Star Wars by comparison). When you want a truly cohesive story you want ONE PERSON to create it, deliver it and execute it etc.
In 2016, Chris Metzen left Blizzard. At the time when Legion came out. Fast forward and Microsoft is buying Blizzard. I doubt we’d get the real answer but I’m guessing that somewhere between 2016 and when Chris got the “advisor” role that he might, as almost a “fan fiction” when he watched on and saw how Blizzard did what Disney did to Star Wars… and made a mess of “his baby.” This is just a personal theory but who is to say that when the sale to Microsoft became reality he didn’t approach Ybarra and Spencer and said something like “want to have a story to reset the game and get audiences back who didn’t like the mess that Kotick caused?” That’s why Ybarra and Spencer likely wanted Kotick gone post-sale…
From Gamespot: “Metzen is one of the key minds behind the Warcraft universe, having originally worked at Blizzard for over 20 years. He worked on the original Warcraft back in 1994”
So he had 10 years to create the original story we were introduced to in 2004. If he began work on “his version” of a story for the game in 2016, and in 2021 or whatever “sold it” to Ybarra and Spencer, he had five years worth of game story written by comparison. Adding here that he definitely never did anything alone. He can literally check Warcraft Wiki (formally wowpedia) to get information. It has been mentioned at any number of previous BlizzCons that it typically took Blizzard three years before announcing to develop a next expansion, and based on this idea, development for Worldsoul Saga (or at least The War Within) began at least in 2020. IF Metzen turned up with a “saga” to sell to Blizzard (aka " Jackson got an audience with New Line CEO Robert Shaye, who accepted the project, but requested that it be expanded into a trilogy.") then maybe 3 years ago they began working on the saga now just expansion 11, and something Metzen had said eluded to this (right at the start of his announcement before saying there were three expansions).
Also, there’s a possibility that when Metzen did his Auroboros game he got asked by Ybarra to work on “his version of an expansion” (this was in 2022). The above and this are both assumptions that are likely not true, but if work on Worldsoul Saga began “only” in 2020 that would create a rushed end result. If however the broad world building had been completed by 2020, and then the work began on ALL THREE expansions (for a cohesive, back to back story, similar to what was done with Lord of the Rings) then we’re already looking at seven years of development on these three expansions. The other two expansions build on work done previously by Metzen, and who knows… maybe the saga was his version of the “road ahead” before he quit, and he quit when somehow they forced in the “kotick version” (aka how Kathleen Kennedy did her version of Star Wars and that more and more they seem to go with “what George Lucas wrote” over there). Now Kotick is gone the game CAN go back to its roots… and to being “Metzen’s baby.”
If Metzen had a story planned before he left and just built on that to get a story to “sell to Ybarra and Spencer” then add an extra 2-3 minimum to it… so up to ten years, so easily the broad strokes for three expansions (plus all the world revamp too if wanted as a side project).
I state all this with some knowledge of how story development happens in general and also awareness of news in the movie and game industry that I read about often. Conclusions of how “other people” do something can logically be applied. Unless they’re reinventing the wheel at Blizzard and literally have gone back to their roots of knowing nothing like in 1994 the people there know what they’re doing. Also, Auroboros was created from scratch (I watched the project’s evolution after its announcement). It was done with other people but the core skill of creating a whole new world came from Metzen’s mind). So I’d believe it when they say he has had a hand in developing Worldsoul Saga…
