Yepoleb: GOG Database collects data from the store pages and Galaxy APIs and makes it accessible on a single page for each game. Currently its uses are a bit limited and mostly developer focused, but I have many ideas of features that could be useful for all players.
Nicely done, it looks very useful indeed. And thanks for making the source code available! I find your use of sqlalchemy especially useful for my selfish purposes - I always wanted to figure out how to use it (by looking at a working example), but was too lazy to research it until I stumbled onto your project.
I'll have an in-depth look over it and may come up with some suggestions later on, that is, if you don't mind getting some feedback :).
Your RESTful API skills are probably better than mine anyway, but I've also been collecting and storing API data using python scripts for some time now, so I'm aware of several quirks and traps GOG API data can shove at you - should you find yourself wondering about anything at any point, do reach out to me, I'd be glad to help out if I can.
