It's an unusually bountiful harvest from the Xbox One backwards compatible farm today. Three huge EA games are now available: Dragon Age: Origins, Battlefield 3, and Battlefield: Bad Company 2.
Dragon Age: Origins is one of the better RPGs to come out in recent memory, and may be of interest to Xbox One owners who have encountered Dragon Age: Inquisition. Similarly, both of the Battlefield titles are worth checking out for anyone who is (like me) basking in the glow of Battlefield 1.
