Hi, thanks for the tool!
It works well (trying to list my GOG library of owned games) except it only lists 404 games, not the 457 that I own.
Two reasons: (1)
MaGog and GOG count games differently. MaGog counts items as they appear on the GOG store catalogue, whereas GOG counts them as they appear on your library, which is not necessarily the same thing. I can't see your library, so I can't bring examples specific to you, but here are some general examples:
- If you own "Wizardry 6+7", MaGog will count this as one item, for that is how it is sold, whereas GOG will count this as two items ("Wizardry 6" and "Wizardry 7"), for that is how they are listed in your library. This is called the "Unbundling effect"
- If you own both "Beholder" and its "Blissful Sleep" DLC, MaGog will count this as two items, for they are sold separately, whereas GOG will count this as one item, for that is how it is listed in your library (the DLC as part of the game). This is called the "DLC effect"
- It's a bit more subtle than that, but these are the two major effects. (2)
MaGog is currently functioning in "Legacy mode", which means that she ignores all games added to GOG in the past year or so (a sliding window, updated once a month). This is done as a pointless protest against GOG having games with in-game purchasing on its catalogue. This self-crippling limitation will be lifted when GOG removes Gwent from its catalogue, or does something equally monumental (e.g. begin selling DRM games, or single-player games with in-game purchasing).
- This means that if you own any games added to GOG since September 2019, they are not listed on MaGog. This is called the "Legacy effect"
Bottom line, you can't compare the two numbers, as you did. They will almost never be the same.
