This attitude is what unduly gives FPS as a genre bad connotations - it's the viewpoint that FPSs can't be innovative, can't do something drastically different, or in general can't be different than run 'n gun. This is a false dichotomy of genre definition here, all to distinguish games - that's what genres are for, to classify games of similar characteristics. Being unhappy with a game fitting into the description of a genre does not make it not in the genre. That would be like someone calling Iron Maiden 'rock' instead of metal just because they refuse to not like any metal.
