If there is one outcome, remove the guise of control. Have my character speak for me. I don’t fucking care. I’d rather feel like my character is doing or saying something I wouldn’t personally do than for me to be given a fucking pop-up that means nothing and is just there to reinforce a self-insert facade. At least make a bit out of it if you’re gonna do it. It’s genuinely one of the worst pieces of game design outside of legitimately predatory behavior.
You should look into Age of Decadence and Colony Ship. They care very deeply about choice and consequence and it's reflected in the writing and quest design.
