What are some great game design tragedies

That is, cases of things being bad but only because the players can't help themselves, when they could easily be good if everyone just tried

For example
>game is infinitely more fun and memorable with a self-imposed challenge like no fast travel
>everyone will use it all the time, complain the game is not fun or memorable, and complain if there's no fast travel

>game is infinitely more fun if you don't look up anything about it
>everyone will just use a guide and then claim the game didn't challenge or surprise them

>etc
