WoW players hates FFXI players and vice versa, also this haters (from both side) never actually touched 80% of the other game..

from my point of view (i played FFXI for 6years before someone goin to call me a WoW-fanboy):
WoW is alot harder and engaging than FFXI, but i never really preferred WoW's graphical style and world, mostly because i played another FF series which i can easily relates to when i played FFXI.

Both games has pro/cons, it just matters of preferences, calling one better than another is just plain ignorance.
