I was thinking about this, and my advice to VR is no tangible assets as it concerns being able to discern ones location in the game. That is... ZERO indicators... No maps, no command lines to discern x, y, z, axis... nothing. Make people learn via landmark. Make people know locations by relative nature. Make them say "Hey, we are over by the old statue of Tunare... not "We are over at 570 x 390 y". People want immersion, then give it to them, not this "easy mode".
