They can't be curious about your character because that would mean taking into account all the interesting permutations that would entail.
perhaps having the opportunity to tell the game parts of our character’s story would set expectations about how the game responds to it that it would be impossible to meet. But until proved otherwise by experience, I’m going to continue to feel that it would still be better to be able to express it, even if the game couldn’t really do much with the information. And at the very least it might prompt more folk to think about who their custom character is and to roleplay that, rather than expecting the game to tell them and be disappointed when it doesn’t.
I think it would be the opposite. I think that the game giving us options of what we can tell it actually sets just the right expectations for what it's capable of allowing. Pillars of Eternity had a haracter right at the beginning ask us who we were and why we were travelling. I think that helped set my expectation of what ort of things the game would allow and was capable of handling.
Considering what an important pillar of roleplaying customizing your character is, I feel like putting more time and effort into making the world more and more capable of handling it should be more important when making crpgs. As much work as goes into classes and combat abilities, more even, considering they take up probably more of the gameplay.
I'm never not disappointed when I reach so quickly limits of the worlds ability to react to the choices I've made about my character, and delighted when really arcane combinations lead to unique story beats.
