i played zero3000 before and quited after 3 days after reaching level 150 .. sure leveling isnt that hard there.. specially if you have good items and a mentor.. but the only downfall in this game is the very HUGE penalty for the one that got Pked .. i mean when you reach lvl 100 and above your a sure target for the PKers .. cuz 1 reason being a PKer in this game has low penalty .. the one that got killed by the PKer droped many items and about 30% to 40% gold you have..
and i think this game has no rules againts KS .. i was just leveling in one spot when this guy using a flamethrower goes to my spot and kills every mob in sight jumping from one spot to another dont care about others leveling there and even killing the mob that another player is attacking ... and another thing the space your provided for inventory is REALLY REALLY REALLY small.. i mean i cant bring more than 20 ammo box or i wont be able to pickup any drops.. well i think those i mention are personal hate about this game.. but you can judge for yourself about the game ...
