I tend to believe all of this. It honestly sounds like every company I've ever worked for in that from top to bottom there's tons of disharmony and a lack of direction.
It also sounds exactly like what Blizzard has been producing. Does anybody remember the last BlizzCon? "You people have cellphones right?" for Diablo Mobile
Virtually every video game decision Activision/Blizzard has made since the success of WoW has been about making money, not games.
Anybody remember Starcraft and how successful it was? Does anybody truly think breaking a complete game into 3 individual paying transactions was done for the sake of gaming or money?
Anybody remember Warcraft 3 and how successful it was leading to the birth of the MOBA community with original DOTA. Where's the innovation? Where's Warcraft 4? It's locked behind a paywall called World of Warcraft where the company is actively looking to drain every cent out of their 10 year old product EVEN RELEASING IT AGAIN versus making new IP
Trying to sell Necromancer for 20$ in Diablo 4? That a move based on gaming or money?
Overwatches commitment to frequent themes targeted at loot boxes, is that gaming or money?
Blizzard has been on their knees sucking the almighty dollar since they went public, they will never be the same again.
This is true - you didn't even mention launch Diablo 3, which was as cynical and terrible of a product as you can find in all of gaming ever. If it was named literally anything but Diablo it would have gone down in flames as it deserved to.
That said, Blizzard was never the "innovative" company. They swooped into an established genre late and released an ultra polished and playable version of it. Even Diablo 1, a genre which didn't really exist back then, was a game (and studio) they purchased as it was close to completion. Diablo 2 was like the Blizzard version of Diablo 1 in that regard.
The high water mark of this approach was WoW, but I also think WoW is what kind of killed them as a company, as it required so many new people that the culture changed irreversibly and brought in so much money that it became a major focus of the people in charge.
I just don't trust Blizzard to make a good Diablo game, and luckily there is stuff like Grim Dawn and PoE which are quite good and well supported. It's not 2004 anymore.
