For this round I decided to take on one of my favorite games i ever played, which is Command and Conquer Generals Zero Hour
I built 2 USA-buildings, a Command Centre and a Power Plant
I built 1 Chinese building, a War Factory
I built 1 GLA-building, a black Market
I also built a coaster which has its station in the command Centre, gets accelerated out of the hangar, in which newly created Construction Dozers are spawning, travels through the chinese War Factory and the GLA-Black Market, before it returns to the hangar of the Command Centre.
