I would like to play the game too , is it possible to get a answer from the company itself ?

A better way would probably be to http://www.gamesas.com/eng/contact_email.php.

I think it is because of 1C company has exclisive rights to sell the game in post-Soviet countries.
I can't see the game on Steam here in Russia too.

I don't really get these "Selling right" things.

To me it's just a very good way to ENSURE that your game gets pirated.
