Johny.: Hey, I see some nice work done there! :) You must have spent lots of time on it. :) I see you've used colors, shadows and font from the site. For me it's always good to see our community involved.
I wonder if it will grow, since it's open source.
Yes, I used a lot of style elements from the GOG site to make the site look more familiar to visitors and because I really like it. It's modern without being too minimalistic or wasting a lot of space. Not sure if the open source license(s) will help the site grow, it didn't really work with the API docs and they're really easy to contribute to, but I've already had some people use it as a reference for building their own stuff. Thanks for the kind words!
Yepoleb: But I just remembered another method. The account page has a store link for every game which gives us the last bought pack that contains the game. If we can convince a few users with massive libraries to "donate" their product list that should cover pretty much everything.
adaliabooks: I've had a look, unfortunately the functions that retrieve those URLs only work on owned games... I'm trying to see if there is a work around but I'm not confident there will be...
I don't think a workaround is necessary. I already know someone with access to about 1000 games and finding the remaining half shouldn't be much of a problem. Maybe Barefoot Monkey can help us out by modifying his script to allow uploading the library to GOGDB in addition to GOGWiki (or you do that). We'll see in the future, because I'm still far from being able to handle non-store games.
