Microsoft have revealed this month's Games for Gold titles - available for free download from Xbox Live. First up is Magic: The Gathering - Duels of the Planeswalkers 2013 that you can go download now, and later in the month it will be replaced by Rainbow Six: Vegas (from September 16).
Perhaps not the most groundshaking titles we could think of, but hey, it's free and once downloaded they are yours for all time (well, in theory).
