Wrong. All those MMORPGs you mentioned suck ass. The only online rpg which is open-ended, customizable and fun enough to make your time (highest of quality time, I must say) worth spending with is UO. Not to mention its scripts which can be freely modified to create a whole range of gameplay options. No freeserver of UO is like another.
Other MMORPGs are just boring. UO is one of the ugliest online games available nowadays, maybe losing only to Tibia or something like it, but no online game is able to provide you as much fun as it does.
I've tried Lineage, Silkroad, Guild Wars, Ragnarok, Conquer, Priston Tale, and others which I can't even remember the name. None of these was able to keep me interested for more than a week, well, except for Silkroad because of its whole Chinese theme. Still, I think I didn't play it for more than a couple of weeks, and then I was just bored.
It is funny how such an old and ugly game as UO is actually able to take your standards so high that most every other MMO you play afterwards becomes boredom itself.
Perhaps the only other MMORPG to get me interested would be WoW, but the hell I'm gonna spend my money with an MMO.
