It'll be interesting, that's for sure. Whether or not the gameplay is any good, i.e. if it doesn't retain every MMO gameplay trope from EVE to WoW, then perhaps it might also work. As long as Bethesda's hands are off the development, then I know that it'll be better than Fallout 3, though, so at least that'll give it a better chance. Also, at least Interplay still has Chris Taylor, so it won't be a virgin team in the Fallout setting a la Bethesda in FO3. On a side note, Fallout Online also has the best game acronym ever: FOOL.
