Well I like all those games. A few of them, I even love. I don't see why they're unimpressive.
imo its because so many people now seem to define themselves by the particular bits of trashy popular culture they consume (including video games) and so then when someone likes what they dislike or dislikes what they like it becomes a personal attack, an attack on their very selves. This is pretty funny because its all about video games which are just fancy toys.
