Unpolished game
This game is fun if you are into ARPGs and the large and detailed world makes for great exploration. Combat is enjoyable if not repetitive, but that nature of ARPG. The loots are also good.
Now for the many many bad things about this game. First its very buggy with problems ranging from small graphical glitches, broken quests and worst unable to start the game! Secondly the interface is not user friendly. Thirdly many features you expect to be in the game isn't like a pause button and in game option menu.
I've listed only a few of the issue, check out the official forum to see a whole bunch of others that other players are encountering.
In summary, as it is now it's worth waiting to see how future patches improve the game.
