Really an awesome game. It's by no means perfect, but it's still a great sandpark (sandbox-thempark hybrid) MMO.

The good:
-visceral action combat mechanics
-exciting open world PvP and large scale GvGs
-multiple ways to progress your character (freedom of endgame)
-the world feels alive and immersive
-great graphics

The bad:
-lots of pop-in
-bad story and voice acting
-gender lock
-Limited player-to-player trading
-No challenging PvE, heavy emphasis on grinding (either mobs or the various systems)

The neutral:
-Being in a guild greatly increases your mileage with the game
-The game demands a lot of time investment; not pick up and play
-You're expected to partake in all the systems, rather than focus on one. (You can't focus 100% on PvP)
