I feel like "dialog" (and duration of recorded voices) and "motion capture" should be on that list.
Like useing Voice actors, and actual actors to capture motions with.... are probably big costs too.
Something like Celebrity status, should be a sub catagory for each as well (voice actors and characters ingame), as they will likely cost more.
Like this is part of why Nitnendo games are much cheaper to make.
Something like Mario Kart World, probably took like 1/3-1/4th of the developers to make, than a Sony Studio would use to make a AAA game.
Ontop of that, voice acting is very limited, and they don't use motion captures ect.
What I'm trying to say is Nintendo makes tons of profits on game sales... much higher than Sony or Xbox.
While their games sell crazy well too.
