My citation is myself as amateur game developer.
Game design is the entire driving mechanism behind gameplay. Difficulty just plays around with the variables that you already have made for said game design.
Do you really think they completely redesign a game for every difficulty?
It is balancing at most.
I designed games myself. It is very easy. Just switch around some variables.
Every game does it like that, whether it is HP, damage, enemy spawns, probability to take a specific action, … it is all just playing around with variables.
It is neither lazy nor not fun.
Did you really think they completely redesign a game for every difficulty?
It is you that has no idea what you’re talking about.
All of them did before, so why not?
Because you can’t scapegoat an AI when the business does something illegal.
