Guys I found a way to do this. Its not easy to transfer money from Paypal to webmoney but its possible.
You will have to pay a fee which is 20% of the amount you want to transfer. If you want to transfer $20 lets say, it will be $5 fee for processing. So the game will cost you $17.33 + $5.00 = $22.33
It sucks I know. I will look for other options, but most options have a fee. If you want to do this, this is how you do it.

Also don't blame 1C company. The Russian version of the game is meant to be bought in Russia and countries of former soviet union. Webmoney is a Russian company.
I am very thankful that they accept master and visa cards, or else I would not be able to buy it. Most of the world has a master or visa credit card, so actually 1C cares about its customers.
Found more websites that do this.
