What I found funny listening was that I heard Demons Souls being an example of a difficult game when the accessibility topic was being discussed. I sincerely think that game for the most part is very fair in regards to the difficulty. You cannot go bursting through the level like Kratos or Cole McGrath thinking you can steamroll everything. You have to strategically plan each encounter with even the most basic mobs, because you'll have your **** wrecked if you don't time your attacks/blocks or try to take on too many enemies at once.
When I think of unfair gameplay, I think of something like the original Ghost n Goblins, or so many of the NES games that were ports of arcade games, meant to be artificially and unfairly difficult for the sake of wringing kids out of their quarters.
I definitely think right now is a fantastic time to be a gamer. There's such a wide variety of game types in terms of genres, difficulty, and length when you consider the range of AAA titles all the way down to the smallest of indie games. Any person who is curious enough to look for it can find their niche.
