MMOs, What makes you like them?

[Ngjoko]

i like RO because it's complicated but not impossible to understand and/or obtainable. The game is cute. Simple animation, complicated mechanics.

I dislike others because it's too realistic looking and i don't know why, but those 3D MMORPGs bore me. Probably since they look good but they only have limited movements and actions. For instance, i didn't even get to level 10 on Tantra because it bores me when the character is hitting on caura or whatever it's called. Perfect World doesn't make me awe in amazement, some weapons are silly, slingshot on archers?
