Dark Urge has a backstory and it worked out beautifully. I much, much prefer playing Dark Urge to Tav now. I played Tav once, tried Durge, and never looked back. There are people who like blank slates, and they get Tav.
Dark Urge isn't that dark. You can be a good Dark Urge. You will have "urges" and make mistakes sometimes, but it'll be revealed in due time why it is. And the ending for a good Dark Urge is very rewarding and wholesome. I really recommend trying Dark Urge. You can change their class and race, so you're not stuck playing Dragonborn.
I'm sorry but I cannot buy the claim, just on face value, that the Dark Urge is not that dark, and that there are such thngs as a "good" Dark Urge with a "good" ending. I need convincing, based on facts from the game, because everything I've read from a range of sources thus far paint a very different picture. Furthermore, as some others have already stated right here in this thread, playing the Dark Urge does come with having to deal with your character being associated with some pretty horrific actions. And to me, it does not matter if those "dark' things are in the character's background or in the form of dreams. Playing "good" means, for me, not having my character associated with such horrible and nasty things.
Larian made many, many mistakes with BG3, including some really big ones. But arguably their biggest mistake was creating the Dark Urge option for players, thereby demonstrating that they *could* provide such an option if they wanted to, and then *not* providing an equal and parallel 'Light Urge' option.
