Is the price in rubles the same? Does Age of Wonders 3 still cost 599 rubles? If yes, then another case of the ruble becoming even weaker.

I track prices only in USD.

OK then. 11 days ago, I calculated that 599 rubles equalled to $11.5. A similar check today has the price as about $10.3. Judging by the way that the ruble's value is falling with such speed, it's very possible that GOG lowered the price ($9.79) in preparation for even more degradation.

At this rate GOG will be implementing a system like that used by TOMS shoes - buy a game and a poor Russian gets a free copy of the same.

Yes, it is. It's interesting every now and then to see how these values change over time.
But if it's a lot of work for you to create these lists, I could live without them.

Anyway, I would like to thank you for your great and ongoing work, keep it up :).

Grin.... I would prefer a system where, when I buy a newly released game at full price, a poor African or South Americanfamer gets some seeds or a goat...

I'd back that!

Thank you.

Hardly any work involved. The lists are auto-generated by MaGog. I just copy-paste.

How often do the currencies change in terms of GOG altering the pricing?. The AUD has kind of died in a bad way last few weeks :(
*looks at the Dead State RU price compared to USD...got to be kidding..geeez...*

Decided to make the rest of my list of shame as a mix, so here you go, Flat-priced games with regional-pricing developers/publishers. See it as complementing Sinistar's mix for people wanting to really send a message, same way that post adds to this thread's OP.

Mix does not include the titles of discount-only companies.

At the moment they're thrown there in the order they are on the list, will decide whether I try to arrange them alphabetically or not, but first will need to decide what explanations to add. Will take a while, no guarantee I'll get around to it.

Will need to make that post its own thread too, and split it in parts.

What, the penumbra collection is back?! When did that happen?
I thought it was removed because gog wouldn't allow old games to be regionally priced. Now even that isn't true anymore?

Everything is slowly moving to regional pricing on gog.com :) Even some older games.
