No sooner has a new style or game mechanic become all-the-rage than we grow weary of it and start to regard it with the sort of scornful scowl normally reserved for a parent at a birthday party. You know: the kind of goofy dad who needs to drink up and leave so that the rest of us can kick back and start having a good time. Right now, cooperative play is enjoying a certain flavor-of-the-month status and developers are falling over themselves to include it in their games, even to the extent – in some cases – that it takes priority over single-player gameplay in terms of design theory and development time. Not too many complaints have been heard just yet but is it possible that co-op might soon go the way of previous fads like (cover your ears, kids) the dreaded "QTE"?
