Microsoft has said you can get 10 free Live Arcade titles if you convince a friend to buy an Xbox 360.
If you have a chum who fits the bill, then pop over to the official site and fill out a festive form together. Just provide the serial number on both of your consoles and a sales receipt to show that your friend splashed out between 1st October and 14th December and you win.
Both of you will be given Every Extend Extra Extreme, Sonic The Hedgehog, Street Fighter II Hyper Fighting, Bomberman Live, Marble Blast Ultra, Spyglass Boardgames, 3D Mini Golf Adventures, Small Arms, Assault Heroes and Zuma Deluxe.
Given the Christmas line-up it shouldn't be too difficult to persuade them, either, but then we are WILDLY TEH BIAS so don't listen to us.
