One nice feature on Xbox One is backwards compatibility support for Xbox 360 games (and original Xbox games soon). If you own older titles on-disc or digitally, you can play a growing list of these on Xbox One at no extra cost, which is a pretty nice option to have. Even if you don't use it all that often, it's nice to know it's there.
"I see games as an art form," Xbox boss Phil Spencer said. "Console games can get lost when hardware generations go away. It can become more challenging to play the games of our past," Spencer said. "There's something to be learned from experiencing what I played as a kid. There's good business there for the content owners, but as players, it's nice to be able to understand how our artform has progressed."
There are currently more than 400 Xbox 360 games that play on Xbox One through backwards compatibility.
