Some people don't like FFXI cuz it can be very long and takes a long time to get stuff. Leveling also takes a long time, but then again it is after all an online game so naturally since you pay for it months at a time...I would think it was kind of meant to have very hard stuff to obtain and take a lot of time to do it. Especially since you need to work with other people to get one item (MMORPG). Come on tho would SE make something easy for us?
WoW I have never played, but FFXI I did for 2 years. I quit tho cuz I got too addicted, but I may be back someday I just dunno when.
I have heard WoW is easier in lvling and obtaining stuff, but then again it's all about preference.
I like FFXI tho cuz it takes a long time to get stuff, and the stuff you can do never really ends so you get what you pay for. Multiple jobs especially I like. (Thief and Ninja are my highest lvls and by far the most fun to me). They also have higher lvl cap then WoW. I think WoW is 60 while FFXI is 75.
If you want to see flame wars on FFXI vs WoW...I have the perfect site you can go to lol.
