MMORPGS as in first person or~?
There was only one MMORPG I enjoyed playing and it was Atlantica Online. To me it took a whole new approach, it involved tactics(since you have a party of NPCs and it is all turn base. Don't get me wrong, you can also party with other players who have their own NPC team out there) Me being a big fan of tactic base games(FF Tactics, Ogre Tactics, so on so forth) fell in love with Atlantica online. It is free(well to much of my former understanding when you play it) and has purchasable content, but such content won't restrict you otherwise(I don't believe.) I only played it few years back. With the graveyard shift and other games, I broke away from MMORPGS, just don't have the time for them sadly.
But if you have nothing against tactic like games or sprite-ish graphics I propose giving it a go, you might like it.
Edit: And of course it is free(or should be) so you can't go wrong. Only thing you would be wasting would be your time, not your money. ^^
