Dominions_2 and Dominions_3 has a much greater replay value for many of us because of the multiplayer option.
Currently rumors exist that Stardock will be developing the sequel for Masters of Magic. Their website has a Poll of whether or not Multiplayer should be added for their current game Galactic Civilizations 2. The importance here is that if enough people vote for a multiplayer expansion on Galactic Civilizations 2 it might give them enough incentive to actually make multiplayer available upon release when they develop Master of Magic 2.
So I encourage anyone interested in fantasy TBS games with multiplayer to vote.
