Buying through Xbox Live store.

I buy most of my games through Xbox live Store digital version that I can download. I was wondering however , if my hard drive becomes full can I delete games that I don't play as often and still download them again at a futur time and date if I ever feel
like playing them in the futur. If so how long do I have to redownload them before they vanish from the Xbox live store. Example. I purchased and downloaded Witcher 3 from Xbox live store about 2 months ago. can I uninstall it today to make room on my hard
drive for another game and in a year or 2 from now can I re-install my Witcher 3 from Xbox live store.

Microsoftstore vs Xbox Store

That deal is only through the store. I was just saying that you do get rewards for digital but not as nice as that current deal through the MS store.

 

Thief

50% off on digital - so just £24.99

EDIT: This is from 28 March 2014 through 30 March 2014.

You can download them for free at any time as long as they're still available on the servers. There is no set length of time you have to redownload them.

 

After deletion, the games will be in the "ready to install" section, located in"My games & apps" I currently have 117 games ready for install.
