Yeah, that's about correct, +/- a few cents.
440 rubles = 16,69$ = 12,45€
720 rubles = 27,32$ = 20,38€
I dont't know, but somehow I would feel bad buying this game for 13€ when I think about what crappy games I've bought for way more than that! ED could sell it for 5 times that price and I'd still buy 2 copies of the game (russian & english version).
Honestly, I think that the ED team deserves way more than 17 bucks/copy for all the work they put in this simulation. Let's just hope that many people will buy it, especially at that price!
