You cant really go wrong because its free!!!! But there are some crap things about it i admit.
Secondly. The representativeness of the game is annoying for me i dont know about you but i dont like hiting clicking on one monster and then jump to the next one all the time but i dont.
And i really hate how long it takes to level when your past 70 because thats when you have to start leveling yourself and you have to spend hours just jumping everywhere trying to find spawn and to get the 0.043 % of a level per hit. Now if dosent seem bad enough to you just remember what your doing just
just jumping around clicking on monsters doing the same old move to kill them.(Theres more choice for taoist's)
But apart from all that it is a ok game and you seem to forget about most of the bad things while your playing it. And i times it can get pretty addictive.
BUT!!!! if you can spend the cash dont bother with this. Play somthing like World of War Craft.
