Morrowind was the high water mark of the elder scrolls series and this is a hill I will die on with fervor.
It introduced a ton of content that Oblivion and Skyrim would proceed to riff on.
But, again, this is a 25 year old game. To say "we'll never have another Morrowind" a few weeks after a bunch of ugly firings doesn't seem to acknowledge that we didn't get a "new Morrowind" before that, either. And we never will, because it's a product of a certain historical moment.
But we still got Eldin Ring and Horizon: Zero Dawn and Dragon Age and Mass Effect and Divinity: Original Sin.
I don't see anything to suggest we won't continue to get big budget open world RPGs, even if they aren't in the identical artistic or thematic style as an Elder Scrolls game.
