I think everyone is buying their time til the Star Wars Knight of the Old Republic and Star Trek mmorpg's come out. Oh, and Starcraft 2.
You can try Pirates of the Burning Sea. Or also try Vanguard, I'm thinking about giving that one a shot again, when it was first released it was buggy as hell but recent reviews say that it has gotten MUCH better.
Surprised you haven't gotten Aly addicted to the Sims.
