I just want a MMORTS that has battles hosted by the publisher, as all MMORPGs are hosted by the publisher, as all MMOFPS are hosted by the publisher. Age of Empire Online relies on peer-to-peer connection, so does Dawn of Fantasy. They each allow less than 4 players per battle, contact with other players is limited to trading or a mere battle-matching system. Yet both are marketed as MMORTS. I'm looking forward to End of Nations, it looks like it would have to have publisher hosted servers when it has trailers of 30+ players battles.
Whatever you're designing, I hope it will be competitive to whatever actually happens to be the first MMORTS.
