When will it get to the point when you'll need to at least do this the other way around? (May even be better than the "standard regions + exceptions" idea I had before.) I mean, "Regional price for [game] is [regional price] instead of [standard price] in [regions].", which may then be used with individual countries instead of regions to clear up any confusion. And then could maybe make MaGOG allow selection of a country or up to a certain number of countries of interest to display separately and the rest displayed as different prices with the countries they apply to as tooltips.

The answer is "when I have time to implement it". I am aiming for sometime in 2015, but can't make promises.

Thank you, Cavalary, for giving me the necessary push to do the first step.

Thank you for doing all the work. Still saying GOG should be paying you for this and implementing MaGOG as the GOG search.

Just in case you haven't noticed (I haven't seen a news item about it), all the Telltale games are on a 50% sale.

Accidental sale? Accidental early trigger for a later sale (Monday's picks?)?

Would expect a higher discount for titles which joined the store a long time ago. Aren't these usually >80% off?

I might be mistaken, but the discount rate seem to have gone down. Discounts of 80% and more aren't that common as of late.
That or a sale proposed / planned but eventually not implemented...

We'll see soon enough ;-)

From the Telltale games, "Tales of Monkey Island" had a 90% discount in June 2015, and the "Sam & Max" games had a 90% discount in January.

During the 2015 Summer Sale, at least 155 games had discounts of 80% or more. Can't really say if this is more or less than previous years, but it does sound a fair number.

But outside of the big periodical sales, what bout the discount rate of the weekly promotions ? 50-60% with the occasional 75% seems to be the bulk of what we see. Might just be a perception of course...

As for the Telltale games, they indeed tend to come with large discounts from time to time. . Perhaps because they're grossly overpriced to start with...
