Stephenson doesn't want to make a complete game with this Kickstarter, at least not yet. It will launch as an arena fighting game, using Razer's Hydra controller, which measures both orientation and position in 3D space using a weak magnetic field. The arena game is really just an excuse to build the toolset that other developers will need to add realistic sword fighting to their games.
