Just noticed this when loading up the Xbox today.
Subscribed with the free 14 day trial and immediately unsubscribed to make sure there were no auto-renewals.
This has come up previously - see here
Xbox Game Pass gives you unlimited access to over 100 Xbox One and Backward Compatible Xbox 360 games for $10.95 per month.
All Xbox One users (no Xbox Live Gold required) can start their 14-day free trial and enjoy over 100 titles. Note that you have to install the full version of each game to play.
Permanent deal, always available.
Pretty stoked my full year of free Game Pass hasn't been revoked though. Thanks again to the guy who put that up.
