Anyone else heard about this game?
Apparently it's been in development for a very long time, and still has quite a ways to go, but as an RTS fan, this has to be one of the coolest concepts for a game I've seen in a long time.
Basically, it's your standard fare RTS game, harvest resources, build bases, build armies and steamroll your enemies, etc...
Except with Achron, you have the ability to issue commands in the past, and in the future, as well as time travel many of your units to whenever you'd like. Definetely worth checking out their page anyways, they've got a few demonstrational videos up.
