Add Russia as region
Add Russia as region in release date. A lot of Russian exclusive games out there, and also those that do came out to the rest of Europe.

Another example: https://www.igdb.com/games/reborn-online, which is currently only released in Russia, but not worldwide.
Example: https://www.igdb.com/games/besieger/ was released in Russia on 2004-04-21 and worldwide on 2004-05-28, but I can't specify that the first release was only in Russia.
