Returning mourner here to get his copium fix. Recently started replaying the game from scratch as I couldn't bring myself to finish it so far.
However, I've also been deep-diving Rogue Trader since before it launched. While it's comparable to BG3 in terms of its technical state, y'know what this absolutely grimdark game is better at doing? Giving and, with appropriate amounts of work and difficulty, fulfilling hope in a logical manner and within the limitations of the canon. In a universe where lives are worth pennies on the dollar, you can actually make things better for everyone while still being in keeping with the overall theme of "only war." Yes, there are repercussions, yes, it is difficult, but that only makes it all even more compelling and satisfying.
WARNING: somewhat major spoilers below even though I tried to keep them as vague as I can.
You can give 'the proletariat' rights and improve their living conditions to the point where almost everyone starts believing you're a heretic.
You can have a wonderfully heartfelt relationship with an initially (very) racist Aeldari if you work for it, even though it's bittersweet in the end - which is to be expected and 100% justified by the most basic of elements: lifespan differences.
You can help a member of the Inquisition hold on to his humanity despite the entire world pushing him toward giving it up.
You can even collaborate with a Drukhari and earn their respect (and a form of friendship) while not renouncing your morals and principles.
In my opinion, a to-the-core 40k story which not only allows, but bolsters humane choices while entirely respecting the canon's ethos only serves to raise further questions around BG3 and its confusing lack of choices around a lot of elements. I still want to give the benefit of the doubt and believe said lack is a result of rushing things to market, otherwise it's just bad writing... I would also like to believe that a Definitive Edition - Hel, maybe even DLC, although that feels like asking for the whole arm when needing but a finger at this point - is in the works, that they won't just leave it at that. This game deserves more respect than that.
