I don't really consider that to be "simulator sickness" fatigue - it's just exercise and fatigue in general due to the course of the simulation, not because of technical flaws in the implementation of the hardware. Though I can understand where you're coming from; I recall really "playing" Dactyl Nightmare in the mall (most people would just stand around and stare in the game - it was kinda stupid), and I would walk away fairly sweaty from the "workout" of playing the game (crouching, moving, shooting, aiming, etc). I always thought that was one of the best aspects of VR gaming - that I could actually be in the game, and not just viewing it through a window semi-passively.
