Good points, good links. True, this is a time traveler's Starcraft/Warcraft/Command and Conquer, etc. On the Achron website they state: "The company's innovation will create new sub-genres of games, starting with the game Achron." Achron is in the MTS sub-genre of RTS, to be pedantic:) However, the scope of differences in here make the term "sub-genre" seem unfair. The new time related gameplay will demand a huge new strategic skill-set from the players. I don't think this will be true for Starcraft II. And you won't be able to learn this skill-set by playing any of the "old-school" RTS games.
