"It is (and always has been) up to game developers to do demos for their own games," wrote Larry "Major Nelson" Hryb on his blog. "They'll [sic] be more demos for Xbox One as the platform goes forward." Hryb was later asked why Microsoft changed its demo policy, but offered no response to that question.
Hryb's statement came in response to discussion of Peggle 2, a recent release that offers players a free demo. That's good, but problematically the Xbox One interface does nothing to separate what were previously considered Arcade games from their retail brethren. As a result, finding the demo is more difficult than it reasonably should be.
