As anyone that has ever read any H.P. Lovecraft will tell you, there exists within mankind a size to sanity ratio.
Facing off against MGS V's 15-metre tall, unpronounceable Metal Gear Sahelanthropus might test our robot-killing skills the maximum, but – save for the occasional rage quit – we can keep a cool head, persevere, and hope it's sophisticated AI has an off-moment.
Equally, Resistance 2's Leviathan might remind us of our favourite city-destroying mega-monsters, be it King King, the Cloverfield monster, or Ghostbuster's Stay Puft Marshmellow Man, but he's not enough to distract us from firing our rockets down it's throat when it roars in our faces.
However, there is a limit to what the human mind can take. Much like in the tales of the Necronomicon when any unfortunate character dares to glimpse the “Elder Things”, there is a point when something can be so big as to become difficult to comprehend.
Rather than protect us from such absurdities, video game developers are increasingly enjoying showing off their exploitation of ever-improving computer hardware by having our video game protagonists face increasingly humongous bosses. Not only are these bad guys often some of the strongest and toughest in a video game, but there mere presence is enough for our protagonist to wonder why they're even bothering trying to kill the damn thing. Here are the bosses so big that it's made us question our own insignificance.
