The folks at D-Box in my opinion bring gaming to life. There D-Box Motion Code system makes you feel like you are really inside the game.
If you have been to any major amusement park you have set in those seats that rock you and bump you around. Well the folks at D-Box have taken that concept and incorporated it into seats that has the action happening on the screen synched up with what you are doing in the game.
Pretty remarkable technology for the hard-core gamer. Not all games are supported so check with D-Box on exactly what games they support.
