@jaffaz: I found it fairly easy by using google chrome + google translate. Just got to the origin store while being behind a proxy and it should automatically take you to the Russian site with Russian prices.
For me the price change was quite significant, living in Norway the digital deluxe edition (which was the one I got) costs 105 USD through origin, and I ended up paying 49 usd through the Russian origin store.
For the regular version it costs around 40 dollars, which is still 20 dollars cheaper then the US origin store. It's all about where you're from :P
I got my copy of SimCity from the Russian origin store, it costs ~40 dollars there however to access that store you'll need to use a proxy. Now the game is registered to my account and everything seems fine. Not sure if this is your cup o tea tough.
Holy hell that is ALOT of comments! I'm wondering to see how this turns out, been a little while since a decent point n click (Sam and Max were pretty rad) Just hoping they get the setting for the game right, something geeky and also perhaps modern?
