We check every store before it is listed. That check covers the seller, the checkout price, and that the store has a refund path. The refund itself follows that store's rules. We test the checkout so the price on the row matches what the store charges before tax and payment fees. Each offer shows how long ago its price last changed. Hover that time for the exact moment. The price, and whether the store still has the offer, can change after that. The list opens on the lowest price, which is the lowest offer GameGator is listing. Some Buy buttons are affiliate links, and the store may pay GameGator a commission. A region is where that key can be activated. A platform is where the game runs. A wrong price or seller can be reported to support@gamegator.net. We can correct the listing. The store handles delivery and the refund.

Portal: Prelude, as its name states it, is a prequel to the game Portal. Its story revolves around the pre-GlaDOS epoch, even before she was plugged in. At this time, test subjects were monitored by real Aperture Science employees whose work was tedious, lengthy and repetitive. This is why they decided to build a great artificial intelligence that could both replace them in these difficult tasks, but also take responsibility for many other tasks within the complex and compete with Black Mesa's superiority. All employees of the Aperture Science complex are now eagerly awaiting GlaDOS. Maybe even a little too eagerly, as the upcoming events will tell...

GameGator compares prices. This description, the release dates, and the age ratings come from IGDB. A later date on another platform is a separate release. A date still in the future is marked as not released yet.
