"Children fight with buildings; men fight with troops"...yeah, yeah, yeah, but what the heck else are you going to do against a massive, totally up-graded Titan army? Check out this hilarious battle in which the entire Thor Titan's army repeatedly chases my puny troops in circles around his base and his forest as my econ booms behind a fortress/tower/wall deathtrap. It's an admittedly cheap strat to beat the Titan level, but curiously entertaining nonetheless.
