I don't have real-time pricing—subscription costs shift with promotions, region, and retailer. As of the last major update, Xbox Live Gold was rebranded to Xbox Game Pass Core (same benefits, new name).
Includes Core (Gold) + 400+ games (console/PC) + Cloud Gaming. Frequently $1 for first month (new accounts), then $16.99/mo. If you play >2 games/month, it's cheaper than Gold alone.
Check the Microsoft Store first—then compare. Prices change weekly.
