In traditional fairy tales lmao. In Larian's last game, Divinity Original Sin 2, the two best endings were: 1) you die, and 2) you become a soulless husk, the middle ending was, you become a divine but literally nothing was accomplished, the conflict against the big bad evil continues as if nothing happened...except like a lot of people worship you now even though you fixed basically nothing. And the bad ending was you release the big bad evil just because you're a psychopath...for no other reason. At least in BG3, at least with the Dark Urge Swen confirmed we can become ruler of the forgotten realms...which in D&D is like all of the Prime Material Plane....which, yeah, hell yeah, I'll take that. The absolute last thing I want to do is another generic selfless servant of the people ending where my reward is death or zombification. I do not care, all y'all druids and everything else, have fun getting stabbed I am NOT going through another "good" campaign for nothing. And even when there is a fairy tale ending it's just obnoxious generic stuff like yay, you united all the various groups and whatever and here's like a medal or something...no thanks. I'll take something new and different...VERY few games let you have a real satisfying dark/evil ending that isn't designed to make you feel like a loser. Of the few games with multiple endings some have their endings designed as measures of completionism too rather than actual real divergence...there is only one optimal ending, the rest are just there to make you feel bad you didn't do more.
Just being able to have a real fun evil ending that feels good...I will take that.
I can definitely understand that. My characters don't want to be assholes as a rule, but a satisfactory ending, with very few exceptions (RDR2 comes to mind), has the survival of my character, mentally and physically intact and generally in a good state, as a necessary ingredient. It's really not much to ask IMO. I require neither respect nor power. I'm fine with walking into the sunset, despised by everyone regardless of what I did. But if I only get even that minimal good by being the Realm's greatest asshole, then so be it.
And Larian has a history of unsatisfactory endings. I recall Ego Draconis, where you end up as a captive in an egg-shaped container on the plane of Hypnerotomachia, alive and conscious, but unable to act, with no prospect of change. And it wasn't even clear exactly why. DOS2 was also a disappointment, but it was golden compared to that incomprehensible downer ending. They changed it in a DLC which is nice since in any other respect, I really like that game.
Having said that, I do not believe we'll have to be evil to get a satisfactory ending in BG3. I certainly see no reason to *start* as an asshole and, say, lead the goblins to attack the druid grove. If this game is really good, it will be possible to let my character be shaped by the story somewhat.
