MadalinStroe: When I asked that question, somebody told me that when the Rivals remake, for the original Sorcerer King, was released on GOG, owners of the old version got a coupon for 50% off the new version. So the new version is technically available discounted all the time,
for some people. It's a bug, but that the reason it exists.
Huh, interesting. I think there are a couple "weird" things about this sale. First if's called the "Back to School Sale", But on the same banner, it's called the "End of Summer" sale. The banner is the only place I can find that you can even see the sale items! Usually a page in the general comments will have a link to all the sale items. But this one (in the general comments section) seems to only link to some of the items.
But even the banner click doesn't seem to take you to the games that are specifically in this BtS sale only... it shows you ALL the games that are currently discounted on GoG, with no indication for when that discount will end. Also, 2 days ago there were 9 pages of games on sale. Yesterday there were 8 pages of games on sale. Today... only 7 pages of games on sale! Is this list also the games that were on sale LAST WEEK but are just slowly disappearing?
In other words, if you get to a game off this banner link, you'd better buy it FAST... because there's no way to know WHERE the sale is it originated from and when it will end!
This is just a curious note: I don't like that the game pages don't seem to tell you how long a game is discounted. For example, I often put a game in my basket but don't buy it for a few days. Once it's in the basket, I can't tell when the sale price is going to drop off!
