What are some good MMORPG games to play?

I've tried several. Runes of Magic and Talisman Online both got really repetitive really fast. Eudemons Online was pretty cool, but they give the paying players such a huge advantage that anybody playing for free is basically everybody else's b*tch. My favorite so far is Atlantica Online. It plays a lot differently than the others, and you control a whole group instead of one character, so you get to constantly swap out your mercenaries. That keeps the gameplay fresh and interesting.
