An interesting game idea, might be interesting if they can polish the game a bit. There's something about multiplayer time travel that tickles an odd portion of my brain and causes it to seize up and start drooling. I would liken it to when I look at extremely large and complex math formulas for too long, but I think Meredith would get upset at the reference :-P
(P.S. I love you hun!)
(X^2+Y^2-1)^3 = X^2Y^3
Hint: graph it
(Basically this game allows for time travel in an Real Time Strategy game--think Command and Conquer. Watch the videos and be entertained!)
