The Wyll situation seems especially tragic because I'm not sure what made Larian come to that decision. Was it based the feedback from the EA? Was the outline they had for his story really that bad?
I have no idea by what rubrik the award presents itself, but Baldur's Gate 3 is another situation where I think it's a better storyteller than a story. This is true of Video games in general, but as far as using the medium to tell a story, I liked making choices, and experimenting around how the world reacted to them; I liked a lot of the level design (like the mountain map and the Monastery) dungeons are after all the quintessential storytelling device in D&D, and I liked the characters. So even if the 'plot' didn't end up being very interesting, I would still consider it a good storyteller.
Imo Wyll was partially because of feedback and partially because at the start of EA Larian said they started with the evil and ambigious companions to get more feedback on them and will add good companions later.
But then they ran out of time, scrapped Helia and pushed Minsc into act 3 to still have him for marketing purposes. So they rewrote Wyll and Shadowheart to be good (or at least to have a good option) instead of just having the unfinished Karlach.
