The steam version of Planetside 2 is US VERSION.
If you would like to play on EU version you need to download the game directly from planetside2.eu, and register account there. (Or read work around 2)
Accounts made at planetside2.eu will NOT work with steam version. You cannot create account for planetside2 US because of the region block on registration website.
As of now 21.11.2012 the EU client is rather ****** and most of the time it just doesn't work.
US version seem to work fine for me. Use it at your own risk. 2 EU servers are accessible via US/STEAM client although your account and game is still US .
So you can use US client and US account to access EU server Miller and Woodman. Not sure hows that possible (because normaly you need separate account for EU client but still, it works) ----WORK AROUND----
1. Go to http://www.everquest2.com/
2. Create SOE account (there is no region block there)
3. Verify via link in email.
4. Log in to everquest2.com website
5. Goto planetside2.com and login with the everquest account details
6. You can login to steam vesion of planetside 2 (US) with the same account details.
There is no region or ip block in the game, just in the registration.
1b) alternatively you can use any old SOE U.S. account to login to the game. (If you played any other SOE games like Star wars Galaxies for example :P )----WORK AROUND2----
You CAN use steam client to access EUROPE servers by typing this "environment=psg" at the bottom of the "LaunchPad.ini" file. You will find that file at Steam\steamapps\common\PlanetSide 2. It will turn the US version launchpad into the euro version.
Remember to re-launch the game and 'verify' game files after modification of the ini file.
