RPG or MMO reccomendation's please!

I've played most MMO's out there and they've all turned out to be boring in the long run or just plain sh*t, I mean WoW was good for a long while I admit but it just left me wanting more of something.. the best time for me was just lvling to max lvl. As for RPG's my all time favourite right now has to be Oblivion since it was such a massive game game with hundreds of side quests to do even after I completed the main storyline. I guess what im asking for is just some reccomendation's for any good MMO's or RPG's out there along the lines of the 2 games ive explained that will have me tuned in for longer then a week..

thanks

Eve Online. Try it. Now.

Tried The Witcher?

try age of conan its has so many improvments from launch

I prefer anarhcy online above all else. It requires you to calculate (in later on) to get the "good" stuff on. It's quite complex game, which can be off putting, but in my opinion it brings great uniqueness to it. Also the futuristic sci-fi theme can be off putting to hard core "sword and axe" kind of players.
