"Entropia Universe".
NO!
OH MY GOD NO!
That game is total crap, if you want to be a "payless" member, as in, no paying money, you can't do crap unless you want to spend weeks harvesting "sweat" from animals. And if you do pay, you will use your money faster than you can blink just buying ammo/weps. If you use a sword once it's broken, the guns have overly expensive money. God, there is not a worse game ever.
