Psycho Mantis is actually one of my favorite villains! Seriously though, by the time you get to MGS 4, wouldn't you already assume by the time you get to the "new game/load" screen that there is going to be a psycho somewhere making a Metal Gear, and that you should probably kill this person and destroy their Metal Gear before they destroy everything? We're dealing with Solid Snake! Yahtzee said so himself: If you've dealt with all the overlong cut scenes before, if you've braved through the insane story and plot twists before, if you have given up hope on seeing anything but long, dramatic death soliloquies. . . If you know the insanity is the norm, and that it bugs you so, then why bother getting the next game? it's because you LIKE the series.
