As an MMO? No, as a singleplayer game maybe with some multiplayer? If the story is good and the proper RPG elements are there, that's a big thing for me when looking at turn based games these days and not even stuff that big game devs have put up impressed me all that much.
I think what a lot of game devs miss when it comes to making any kind of game is good scenario writing and level design. It's become something of a lost art as they rely far too much on procedurally generating or randomising their content and think that's all they need to do.
I highly recommend going back to old school games like Half Life and maybe even System Shock and so on to understand what I'm on about. Fallout New Vegas is a game that I still play to this day at times but that's on the more extreme end of very carefully designed game scenarios. Since you were looking at turn based Fallout 1 and 2 would be something to check out too, perhaps Baldur's Gate 2? Depends on what you're into.
