What is Creta Games & Clubs?

Creta Games & Clubs is the Creta game platform: a store where you find and buy games, a library that downloads, patches and launches them, and the community that goes with them — clubs, posts, friends, chat and who is online — all in one place.

It also carries the Web3 side of the platform: a wallet, your NFTs, and paying for content in CRETA.

It comes in two forms — a website you can open in a browser, and a desktop app (the launcher) for Windows and macOS. They share one account and one library, but they cannot do all of the same things; the next answer explains which is which.
