Is There A List Of Games Compatible With Digital License?

As long as the games are backwards compatible, they should work whether you have the disc or digital. To get the digital license you would basically have to rebuy the games digitally, which you shouldn't need to do. Double check that they are all on the
backwards compatible list - https://www.xbox.com/en-US/xbox-one/backward-compatibility?xr=shellnav

Hello

Backwards compatible games will be available later this year for the general public, new games are added periodically and are added to this list as they become available.

Please keep in mind that not all games will work on backwards compatibility due to licensing and rights etc...

If the game is available for Backwards Compatibility both digital and disc versions of the game will work on the Xbox One. Digital titles will be available for download from the "Ready to install" list found in "My games and apps"

I'm sorry to tell you, but it looks like this game will never become backwards compatible. The main reason for this is that the game was delisted from the Xbox Live Marketplace. In fact, it's been de-listed from all digital game stores, which means the
digital version of this game can not be purchased on Xbox 360, PS3 or PC.

Microsoft only release backwards compatible games that are still on the Xbox Live Marketplace. The most likely reason why the game was de-listed is due to licensing. Blur contains real cars from real manufacturers. The license for these cars are only held
for a finite period, which means, unless the publisher renew's the license - usually by making a sequel, it lapses. Hence, the digital version can no longer be sold for download.

It's a legal issue, so it doesn't matter how many people vote for it, it can't be made backwards compatible.

As you've probably seen from the
Backwards Compatible list there are very few sports orientated games available. The reason for this is licensing, and because of a legal dispute between NCAA and EA Games, the NCAA games were de-listed from the Xbox Live Marketplace.

Microsoft and its associated partners only make games backward compatible that are available to purchase digitally via the Live Marketplace.

When you purchased digital versions of Xbox 360 games, those games stay on record in your account permanently. As Smwutches mentioned, there is no manual intervention required to "transfer licenses"; the Xbox and the Xbox account takes care of all that stuff
automatically. It's only a matter of whose account you're logging into, and accessing what that account purchased.

When you log on to your account on the Xbox One, any Xbox 360 digital games rated for backward compatibility will appear on the "Ready to Install" list. Look at Taidara's post for the list of BC games that are playable on the Xbox One. If you have a purchased digital
Xbox 360 game on your account, and it doesn't appear in the Xbox One's "Ready to Install" list, it likely means it's not backward compatible (yet?). When a 360 game is not backward compatible with the One, neither a digital license or a disc will work.

Another player can log on with their account on the same console and download their games. I believe execution of the digital game will solely depend if you're logged on to the account that bought it. You can't, for instance, download a game with one account
(that bought it), log in with another account (that didn't buy it), and start the game -- it will not run (afaik).

If you don't want to deal with all of those DRM limitations, then, by all means, get the disc version of the game. A disc essentially acts as a portable DRM license.
