Judging by 505 Games' other stuff on steam,
a game that costs 30USD costs 50 Lira. So it stands to reason that a 60 USD game would cost 100 Lira which is about 17 USD I believe.
And you're right, this is more a case of MS' regional pricing being absurd than anything else. I guess it's a good thing the game has EGS exclusivity so you're left with one extremely expensive option with even basic functionality having issues and one very cheap option with incredibly few features.
There's a thing you're (understandably) missing with regional pricing, a thing about Steam's pricing policy.
Essentially, if there's another distributor in Turkey that's bringing over a game also sold on Steam,
Steam will match the physical distributor's price.
I've seen literally 2 PC game distributors in Turkey, ever: Bilkom(?), which, to my knowledge, only brought over The Witcher 3, and Aral, which brings over literally everything else (except Switch maybe, which is new).
The Witcher 3 was 70₺ on launch, that's around 20 Euros, more than fair, I got the game in 2015 out of sheer appreciation and literally only got around to playing the game this week. That's Bilkom, and that's fair.
Aral, however, basically has a monopoly on video game distribution in Turkey, and they abused the SHIT out of Steam's regional pricing policy.
Devil May Cry V is 400₺. The minimum wage in Turkey right now is 2000₺ a month.
People in the US pay about that price relative to their economy for a(t least half a)
console.
Octopath Traveler is 320₺.
Dark Souls 3 is 180₺.
Civilization VI is 220₺.
These are prices on Steam. It's worse on console. DS3 is 220₺, etc. (10% of minimum wage income.) Thanks to Aral.
Some games ARE excellently priced- indies are still around 31₺, Yakuza 0 is 50₺, etc.
But especially for AAA gaming, Turkey -like many other countries- was left in the dust, even by Steam's regional pricing (and hoo boy it's worse if you ever had to buy something off of GOG, say, which has no regional pricing whatsoever).
Getting to preorder Control for 40₺- that's fucking
unheard of. Mind you, the closest thing I remember, even to that non-discount price of 100₺ -TW3 for 70₺ as mentioned above- was in 2015, when a Euro was 3₺ or so (it's now 7₺, haa...).
Everywhere else in the world is charged in US dollars.
They do charge in Turkish Lira. I just checked.
