From Slashdot (I won't link to them for fear of overloading their server) I got a link to this gadget which actually lets players experience the blows and wallops as well as the sights and sounds of the game world.
Utilizing air pouches--four on front, four in back--the vest nudges and jabs gamers at eight different contact points.
Now I have to say I think this is hilarious but I can just imagine that this thing could catch on. It has a certain macho cachet: "My game hits back but I can take it"!!! Personally though I think I had better brush up on my head shots before I expose my poor body to this thing.
Mind you - it could add a whole new dimension to Death Penalty in MMORPGs.
