How much drugs do you have to take to bring such an argument.

Adding an easier mode (which changes nothing in your experience or the "vision" of the game studio) is the same thing as walking into a bakery and wanting meat???

Your analogy would be more like buying a racing game and then complaining you can't fly to mars in said game.

But why do sushi restaurants offer for example vegan options?

To reach more customers and this would be the same with games. More accessibility options means more players can enjoy awesome games.

Am I missing something? it sounds so simple for me and wouldn't affect my experience so why is it bad.

And the best thing about accessibility options is you don't have to use them if you don't want/need to and get the exact same experience as before surprised pikachu face
