Xbox Game Pass
In short
A subscription service from Microsoft that provides access to a rotating library of video games for a monthly fee. It works across Xbox consoles, Windows PCs, and mobile devices via the cloud.
In plain words
Instead of buying every game individually, you pay a regular fee to play hundreds of them. It is like having a Netflix subscription, but for video games.
A simple example
A player pays a monthly fee to download and play titles like Halo or Forza without buying them separately. If they stop paying, they lose access to the library.
Why it matters
It changes how people consume games by making many expensive titles affordable through one payment. It also helps smaller developers reach more players quickly.
Easy to mix up
Do not confuse it with Xbox Live Gold (now part of Game Pass Core), which was primarily for online multiplayer access.
