Any good 4x multiplayer RTS?

Hi!

Any good multiplayer real time 4x games out there? I've played Sins of a solar empire, Pax Imperia and Imperium Galactica II.

Hi,
I am working on a clone of the game real time strategy space, that time has no multi player option.I would add to the multi player.This is very long and I don't want to force the players to play it uninterrupted or lose the game state due crash/power outage.
