The backwards compatibility mode on Xbox One is like having a cupboard of forgotten games that keeps being filled. Pop in there today and you may just spy a game or two that you own; Epic Mickey 2: The Power of Two or SEGA Vintage Collection: ToeJam & Earl.
Both games are solid co-op affairs with Epic Mickey 2 offering some old school platforming which requires some true co-operation between players as each character has a different power set. Check out the surprisingly well written review of the game.
The Toejam and Earl Collection may be a little older, but has a classic charm to it and offers two different genre of game for the price of one. We gave this game a higher score than Mickey, but the review is not as well written ... Both games are worth reinstalling on your One if you bought them back on the 360 and will be great in a sale or as part of any future Games with Gold.
