"Players don't finish games because they get bored...It was boring...Quests were simple and boring...It might have gotten better, but I'll never know because I got bored..."

You're kind of sending mixed messages here. You say it's not boredom, then you say you quit because you got bored... But I think I understand what you are trying to say. That people stop playing these games because they no longer expect good games, they expect inspired games. If the games just keep repeating the same thing over and over again it's going to start feeling like work.

I think a good example of the problem of repetition is the game reviews for Alice: Madness Returns, where they said the first 5 hours of the game were flawed, yet fun, and then kept going. And going. By the time they reached the end they were just sick of it. If a designer can't make a game that can hold your interest through the entire gameplay they are doing something wrong.
