Thanks for the clarification.
Yes, I agree that the project should have something more than just Discord. I just thought Discord is quite popular among gamers. I will think about Matrix or Lemmy in the future.
About the account - well, I need an account to be able to record what games you rated and what recommendations you currently have. Otherwise, I have no idea for now how I can show correct data to correct people. I decided to allow people to register with game store accounts because that's easier for me to implement.
Theoretically, I can allow users to be in the "offline" mode, so all their data is stored locally. Data will be lost if you, well, remove it by yourself, or your computer drive dies. The only note is that the recommendation algorithm is not open-source, so you still need to send your data to the server to get new recommendations...
Anyway, thanks for the idea, I will think about it ๐

Well, currently, you must enter every game you played manually. I don't read games from users' account because I don't want to deal with private data for now. I only ask the game store that the user chose to give me the user avatar and public name, and confirm that "yes, this user is registered on our platform and account valid".
After that, I use id that the store gave me to connect you to what games you manually rated on Gamescovery and what games were recommended to you by Gamescovery.
