So you're telling me that mu which has no role playing elements in it at all is in the same class as Lineage, WoW, etc..? If so you're sadly mistaken.
I have this review of MU I like:
"1st of all this is not roleplaying, this is just mmohsg (mmo hack and slash game), killing for weeks all the same monsters is depressing boring stupid and make me just sad... really dont play this game because you will lose your time... EDIT: Someone wrote that this game give freedom in building characters... well absolutely no freedom less that in any other game I saw... and you CAN give points in other stats that they should be - just then you will have to quit playing because noone will have you in party and alone you won't be able to kill anything bigger than a bull. Equipment? LOL You have few armor types, one better than other, not a SINGLE difference, just better armor rating and more strength"
