Monster Hunter fights last up to 50 minutes; 50 minutes of full-on claw-evading, potion-swigging, monster-cleaving concentration. Fingers Riverdance over buttons, rolling and leaping. Eyes dart for safe ground, hungrily searching for the five seconds needed to sharpen a dulled blade. Gobbling meat claws back in-game stamina, but does nothing for your own, sapped after nearly an hour of constant action. As the Classic Controller Pro threatens to slip from your moistened palms you ask yourself: outside of Wii Fit, when did you last break a gaming sweat?
