At E3 2017, Microsoft announced that Xbox One will have backward compatibility with the original Xbox games, however, not many details were revealed. Now, thanks to the Xbox system, we have found 2 games that could be part of the backward compatibility alignment.
So, the Xbox page has in its database the files of Grand Theft Auto: Vice City and Half-Life 2. It is possible to follow and check its profiles in the same way that happens with the rest of the games. They also include sections for captures and achievements. This last section encountered is empty, remember that Microsoft has already confirmed that backward compatible will not have successes.
Using the same account, we played Ninja Gaiden Black, Grand Theft Auto III, Halo: Combat Evolved and Halo 2 on Xbox 360 to see if they appeared on our list of Xbox One games, but nothing happened. The only titles that appeared in the hub were GTA: Vice City and Half-Life 2.
So far, Microsoft has confirmed Crimson Skies and Fuzion Frenzy as backward compatible games. During Microsoft’s E3 conference, Xbox boss Phil Spencer mentioned that the backward compatible games will “play and look better” on Xbox One, although no further details were revealed.
Spencer said in August that he expects to “show more [backward compatibility with Xbox Original] this year,” so we’re not so sure we’ll see this feature in 2017 anymore. It is also unclear whether backward compatibility will first reach all users or only Xbox Insider members.
Another detail we must keep in mind is that the catalog of backward compatible Xbox Original games will not be as extensive as the Xbox 360, which so far has about 400 titles.
The good news is that the backward compatibility with Xbox Original will allow you to use the original disks or digital downloads on Xbox One. In addition, it will be possible to have LAN games and connect an Original Xbox, an Xbox 360, an Xbox One and an Xbox One X using the original game.
