skeletonbow: Number reported when clicking on "ACCOUNT" = 445. That includes a few freebie movies presumably, [...]
Movies are not included in that count, as they have their own separate library tab. (Nor are DLC counted, as they're accessed from the "boxes" of the games they're associated with; and I was also somewhat surprised to find that items you've hidden from your library aren't counted, either.)
skeletonbow: [...] No idea what my current count of actual gog store game products are as there isn't a way to tell anymore in terms of pre-unbundle counts. Probably somewhere around 350-375 depending...
Well, given that the question was "How many GOG games do you own?", and not "How many GOG catalog items have you purchased?" or something, I'm not sure why the "pre-unbundling" count would matter. ; )
EDIT: If you really want to see how many catalog items you've purchased, going back through your
Order History should help. With that many games, it wouldn't exactly be quick, but it
would give you a more accurate impression than your Library count would.
