Microsoft has replaced the Xbox Live Gold subscription with Game Pass Core

The price of the updated subscription has not changed - it is $10 per month. All the benefits of Live Gold are preserved: multiplayer and discounts on games up to 50%. All Xbox Live Gold subscribers have been migrated to Game Pass Core automatically.
