Im thinking about getting two Xbox 360 Slim systems. The Xbox 360 Slim has a wireless network adapter built in, and you can wireless-ly connect to internet through your router. I wanna know that if I get two xbox 360 slims, if I can connect them both to each other wireless-ly and play system link games (w/out the Ethernet cable connecting the two). EX: Could I play a system link game with my roomate in the room beside mine, w/out using wires to connect the two??
