Can you link two VR3’s together so you can play at the same time against each other?
How and whether they can be linked depends on the game you are playing as they are all different. The majority of games are capable of supporting head to head racing between two systems in some way.
e.g. GT5 on PS3 can be linked using online racing although this requires both systems to be connected to a broadband internet connection. rFactor on PC can be linked directly together using a network cable and requires no internet connection.
