The style may appear childish but it is very smooth and plays well
One of the better MMORPGs: ROSE Online (Rush on Seven Episodes) is one of the better MMORPGs I have played.
For credibility: I have played Lineage1, Lineage2, Dragon Raja, Asheron's Call, Project Entropia, Helbreath, Ragnarok Online, Final Fantasy XI, Guild Wars, as well as many other Korean based MMORPGs so I have WOW Power Leveling something to base my experience on.
That set aside let us discusses rose zuly. First of all the graphics to me are very detailed and well polished. The style may appear childish but it is very smooth and plays well. Any item that you equip will change the physical look of your character which is very cool.
Character models appear very well rendered, and while they not be super highly life realistic models, do they really need to be? Visibly the game looks gorgeous and the lands/maps are well developed and I never noticed texture clipping or misalignment; if there was any I was too immersed to notice.
Quests are fun; as fun as quests can be. Sometimes they are tedious but it's like that in most games... and most games tend to leave out quests completely so be glad that rose zuly.
