I love difficult games, I'm an older gamer, games used to be really hard in early 90's.
With that said, games are algo much longer to finish, so I prefer not that hard but hard enough to be a real challenge, If games become too easy, then there is no reason to play, games are made for challenge, if I just wanted the story I'd read a book or watch a movie.
Some people feel the need for easier games so they could finish all the games, the big issue here is people shouldn't play all games, pick 1 or 2 great games per month and that's it. I don't like sports games so I never buy them, and there hasn't been a good racer on ps4 at all, so that's another genre that I don't have to play. I limit myself to around 20 games per year, so that I can enjoy without rushing, without having to chose it on easy mode.
When I review games I drop a star/point if the game is too easy on the hardest mode. I remember doing this for all the uncharted games for example. The worst offender for me was GT sport, the campaign mode is just far too easy compared to the older ones, I remember GT1 and 2 spending hours to get gold, on GT sport I get gold on the first try, it makes the game boring.
