[Guide]How to find out if a game is region locked

This will be a quick guide/tutorial on how to check if a game on the Steam Store is region locked (You can only play the game in the country you bought it). This is a great way to save money on Steam games. As the US store is generally more cheaper than others, and then you can be gifted the game.

1. Open regional Steam storefront with the url:
   http://store.steampowered.com/?cc=uk
   With the 'cc' parameter that set region store you want to browse
   us - USA
   ru - Russia
   uk - UK
   fr - France
   de - Germany
   au - Australia etc. Just google 'Steam [country]' for your country.

2. Click on the game you want to check and position the cursor over "Add to Cart" button

3. Look at browser status bar in the bottom right (Google Chrome). You will see something like this -
   Code:
   jAddToCart(1222)
   or
   Code:
   javascript:addToCart(1222)
   This is for GTA IV

4. Write down this number and repeat from step one but with different cc parameter.

5. Compare the numbers you written down with different countries.
   Different number means that regional stores sell different version, which may be region locked or have a different version of the game.
   If you see same numbers for several EU countries and different number for Russian store then that game is region locked to Russia.

Same numbers for all stores - RoW

Examples:
CS:GO - 16222 - same for all countries
Grand Theft Auto IV - 1222 same for all countries
Fallout New Vegas - Ru=6443, EU=6442, US=6442, AU=6445

Feel free to add example and I will add to list.
