One specific wish for the new game

I want the player's choice of house to actually mean something beyond one singular mission. I enjoyed creating characters for each house on my way to getting the achievements and I even imagined backstories for them.

It would be nice if you choice of house affects how the PC talks and interacts with people, with a more callous and distant tone as a Slytherin to a more patient and level headed tone for Hufflepuff.

Think like the difference between Renegade and Paragon from Mass Effect. There are countless variables in those games, yes. But the tiny differences really fleshed things out and made it feel like Shepard was a character that you created. I felt my Legacy PC was one character with barely any personality or backstory because of how the story presented them.
