With the Xbox 360, you could expect to be able to try any Xbox Live Arcade game before you bought it thanks to Microsoft forcing compulsory demos for such titles, however this is not the case with the Xbox One. Microsoft’s decision to scrap the Arcade Store for the Xbox One means that studios will no longer be obliged to offer demos for their games. In short, there will be no guarantee that digital titles will feature demos.
In a “Ask me Anything” over on IGN, chief Xbox One platform architect Marc Whitten said “Not all games will have demos like Xbox Live arcade games have had on Xbox 360,”
“That said, we are going to work on lots of ways to make it easy for you to find and try new games on the service,” he went on to add.
Demos will still be available on the Xbox One, but as for what games that is something which can not be guaranteed. But as Marc Whitten suggested, Microsoft are looking into ways to ensure that gamers will be able to try as many games as possible before purchasing.
During the Ask me Anything, Whitten also confirmed that you can sign into both the Xbox One and Xbox 360 on the same gamertag, meaning you can be signed into both at the same time. However like the current 360, you can only be signed into One console of each.
