It was surely only a matter of time, since I have so many great ideas. However, to quote from this very blog from July 19th 2006, where I described a time-travel game device: "To give you a more concrete example, imagine Command and Conquor with time travel".
Lo and below, fast forward to 2009 and what has happened? Achron: "a real-time strategy game where players and units can jump to and play at different times simultaneously and independently".
I assume the cheque is on the post.
