Sky Siege Augmented Reality Warfare Game Turns iPhone Into Deadly Portal to the Heavens

Sky Siege ($3, available now) uses the iPhone 3GS' compass and accelerometers to turn the iPhone into a window rather than just a screen, resulting in startlingly immersive gameplay. Don't know what that means? Just watch this remarkable clip. [iTunes]

DISCUSSION

Looks very awesome, but at the same time it seems like it would lose its appeal rather quickly, given the practicality issues. On top of the obvious issues (looking like a fool in public or even at home, etc.), I gotta think having the camera on like this will cook through battery in no time.

IMO the whole Augmented Reality thing is overblown and will become a niche feature in the next 6 months or so. I was excited when Yelp added it, but after the initial experimentation I haven't used it in months.
