I get where the OP is coming from, and it is very nice when our choices are meaningful. However, there is sometimes a benefit to making decisions, even if they don't impact the outcome. Based on the current character creation, our characters come in a pretty blank slate. Sure, you have a background, but those are pretty limited in their detail and often fairly mechanical. Being asked questions gives you an opportunity to express (and often identify) aspects of your character that you might not have thought about otherwise. I don't necessarily want a ton of this, but I find that having "what would you do in this situation?" questions sprinkled around can help immersion. Certainly, these choices should *feel* meaningful (and a more nuanced dialog tree would often be helpful for this), but they don't necessarily need to have a big impact on the story to be useful.
