GreenDigitalWolf: ~764 (?)
After failing to take a screenshot (I don't know why it didn't work), I'll have to type it (Sorry for too many WEs :p).
We go to "Browse Games".
We scroll all the way to the bottom, showing al the pissible purchases in a list.
We Enter ".99" (As all games/expasions' price contain ".99", or that's what I think) in the "Ctrl + F" search.
We get 735 as a result.
We subtract 5 from 735, which represents the games that appear twice (In the list and at the top).
We get 730 and add 34 to it, which represents the games I own and din't appear with price in the list.
We get 764. But I don't don't know if all are games or there are expansions or even bundles.
mrkgnao: This trick doesn't work. Every time you get GOG's catalogue, you get a different list (usually 0-2 games missing, but I've seen as many as 15 missing).
There's obviously a bug in GOG's catalogue feature (probably a result of the annoying infinite load feature).
Trust me, I know. Remember, MaGog gets GOG's catalogue twice a day and counts.
Thanks, I didn't know that. I'll need to check ouy MaGog soon, I've read a lot of good things about it.
