Why can't gamers diferentiate between their personal taste and quality.

I would argue the exact opposite, that a game is good precisely because one likes it, and is bad because one doesn't like it. What I don't understand is when someone says "it's a bad game, but I like it," or, conversely, "it's a great game but I don't like it." If you like it, it's good, at least to you. But you can't speak for anyone else anyway, so YOU are all that matters.
