I'm glad that I'm not the only one who understands and acknowledges Val's seemingly vitriol hatred for the game. As for the 'Barren' thought on it, well.. the only area I'd call barren at all in the expansion is the Moon... which is well... the MOON. Not surprising that there aren't that many quests or activities to do up there.
As for the story itself, I feel like Endwalker is about up there with Shadowbringers, but in a different respect. Shadowbringers was very much a story that could be taken on it's own and away from the rest of 14 and still be considered awesome. The Lore stuff considering the Exarch, the Sundered worlds, and everything else deepen the understand and enjoyment of what came before, but isn't necessary to understand what's a play there.
By comparison, Endwalker is very much MEANT to be taken with the rest of the game in context. This is supposed to be an adventure to cap off all the adventures you've had just far, where the characters you've traveled with, grown with, and fought along side bring to a close what started back in ARR all those years ago. If you hadn't enjoyed the story up to this point, or didn't care about the Scions or the world you've been playing in, then yeah, Endwalker kinda falls flat since it's not meant to be taken as a solo story. But as the end to ten years of laughing, crying, and the scions coming together as a family?
It's near perfect.
