my one regret about gamedev is that it isn't really one of those careers where you can have like a cool defining personality trait that influences your technique. like you can't be like "i'm on a quest to find revenge for my family which is why i use freya holmer's iterated lerp fix"
I think I actually get to have this though as an accessibility design specialist. I got decently known for playing games one handed because of my disability. Starting from that exposure I learned a lot about accessibility needs in games as a whole. Now I apply that knowledge to a wide variety of design problems to create inclusion and undo a wrong most devs aren't aware of.
Not as epic as a revenge quest but I think it counts.
