Black Desert. Currently playing it with my community that is also more of a friendship and we're having a blast. In the past week we've all sunk about 32 hours each in the game so far. It's very addicting, has a lot of interesting mechanics, and it has housing so that's fun.
If you're impatient you can grab WTFast for free and play on the Russian open beta servers (also free) using the English patch. Hopefully the NA beta won't be too far off, either. Though NA/EU will be buy-to-play.
