With Xbox One's backwards compatibility program recently reaching the 300-game mark, Microsoft is offering Xbox owners a nice freebie right now.

Lost Odyssey and Blue Dragon, two Xbox 360 RPGs added to the backwards compatibility list this fall, are now available digitally through the Xbox Store. That means you can play them on an Xbox One or 360 without a disc (or four, in Lost Odyssey's case). Blue Dragon costs $20, while Lost Odyssey is being given away for free until December 31.

The two games were the first ones developed by Mistwalker, the studio founded by Final Fantasy creator Hironobu Sakaguchi. They were 360 exclusives and represented Microsoft's attempt in the mid-2000s to attract RPG fans to the console, particularly in Japan, where the Xbox brand has historically struggled.

Xbox boss Phil Spencer said on Twitter in October that he was aware of interest in offering digital versions of more Xbox 360 games, including Lost Odyssey specifically.
