HL2: episode 1 on the Oculus Rift with Razer's Hydra motion controllers so you can see your hands move? Hell yes. Check out this Half-Life VR mod video from Kiwi YouTube gamer Goldfish highlighting some of the amazing dev work.
Seriously, consider how he's reloading that revolver. "You unlatch the barrel, [physically] flick it over, release the clips, put in the new ones, flick it up and then you shoot." And don't get me started on holding the crossbow site to your face.
