Use a reliable metadata source
June 2019 update:
Since the TheGamesDB API has been deprecated (as reported here), Games has been unable to retrieve metadata, which led to the removal of the Developers view. I have suggested before to drop TGDB and switch to Screenscraper for metadata retrieval (my rationale is explained here), but the database is licensed under a CC BY-NC-SA licence, which apparently forbids us to use it (projects depending on Screenscraper such as Recalbox include a "Commons Clause" on their licence).
I would like to suggest relying on Wikidata instead. The related grilo-plugins ticket is here: GNOME/grilo-plugins#50 (closed)
Former ticket description:
Screenscraper.fr seems to be more reliable and complete than TheGamesDB. How about switching to it to retrieve our metadata?
