Such a big difference?
That's crazy. O_o

Guessing somebody forgot a 3...

From MaGog's logs for 11 May:

NOTE! CHANGED Age of Wonders 3, reg_price_full, SE: $3.76 ***TO*** $34.58

It doesn't cost this little anywhere, so it's quite interesting how the mistake happened.

Wonder how many copies were sold for this price.

Glad to help.

I'm sure the Swedish people love you. ;-)

I believe Cavalary's explanation is the right one.
I guess I'll go buy something at Ikea to compensate them.

Wat. Usually, a game's price decreases with time if it changes at all. Have they perhaps done a major upgrade (e.g. got rid of the squeaking)?

Announced beforehand, there's some giant update coming that adds voice acting, fixes etc.

Probably this:

BTW, because of GOG's bug, the de-facto price is still $9.99 everywhere except US/CA (and of course RU/UA/UZ).
And US/CA get a $10.00 fair price package because the CN price is still $9.99.

Great news. I got the game on release but quit it because of the toothache-inducing voice effects (if you've played Undertale, think Flowey the Flower, except the latter is annoying for a reason).
(Well, the update is great news. The price fuckup isn't.)

Megamagic: Wizards of the Neon Age got released and it still apparently has no RU/UA/UZ regional pricing, as reflected by the first review the game has received.
