I think you ppl misunderstood, single player campaign got inherited into start of mmo part (so it is done in mmo part not in SP). Single player skirmish + multiplayer skirmish are still here and as i said in previous post also different mods of skirmish play. So dont worry skirmish part like AoE or AoM or EE ..... (any normal RTS) have is still here.
Again, Yami-Yagari talked about CAMPAIGN not skirmish mods. SP or Multiplayer skirmish are still here.
