2moons.

[#1]

Taken from the Korean game called 'Dekaron'
Its your typical Korean grind fest game but with added fun!
Its currently in OB ( Open Beta ) and will continue to be FREE
It does require some stumok to lvl up and lots of dedication if you do intend to stay on.
End game atm is well ... There is non Apart from PvP. Hopefully that will change when new content comes.
Heres a link to the site which explains all.

And here is some pvp footage. ( Told you its a grind fest with added fun! )

I'm not a fan of 2moons; I had it installed for all of 30 mins and got irritated by the gameplay.
Also the bad move on Acclaims part (Well, one of the bad moves) was to introduce voluntary VGMs - volunteers to help be gamesmasters. I can see it coming to a point where some of the kids that applied to be a VGM start to help their friends/clans to kill things, give them insider information, etc.

True, it does have it kinks but its free and fun Until WAR comes out.
