I tried it out till i got to lvl 5, and it was tight.
You have to pay for it. Before. Now it's free to play, which is tight.
Game is called R.O.S.E Online.
Search on youtube. Really cool videos and stuff on it.
Make sure you download the right one, some people made there own "free" private servers before cause the original wasn't free, which it now is.
Heres the "official" site of the game:

Don't judge till you try. I judged it being wierd, but once i played, it was tight. You can even ride cars in this mmorpg.
To brownie:
It's somewhat like tricksteronline. Except 3d and you can ride cars. You can customize cars.
