Would've loved to play TW3 as a member of the Scoi'atel or something. Geralt's boring, from personality to backstory to how the world reacts to him; there's some "omg hes mutant" but it doesn't go beyond some spitting and whatever, like, it can be totally ignored. He's like an observer to the world, no real motivation or belonging to anything. As a scoi'atel there'd be so much more stuff and agency and motivation to do things instead of just "I kill monsters guys."
