Yes, I have (and have finished) the Russian version. My system is good, but nothing special: C2D 3,2GHz, 2GB RAM, 8800GT. It's not a very demanding game, it ran very smooth for me at 1920x1200 with maximum details and antialiasing. Real-world system requirements should be even less than specified on the box.
The game is very good, certainly one of the year's best. My only major worry is English localization and how the tone of the game would be translated. There are some smaller issues, like weird game balance (it starts out very hard and gets easy by the end), and a few bugs, but other than that it's great. You can tell it's a labor of love.
Oh yeah, one more thing: I hope the English version has better intro and end cinematics. The game itself is quite beautiful but the introduction and end are rather 1990ies. Devs, please take a hint from Blizzard there!
