Tiberium Origins lets you play all four sides from Tiberian Dawn and Red Alert in one game, plus two more. It features Tiberium as a third resource, more valuable than ore and gems, bringing a new gameplay element to command and conquer. All four sides have their original units and structures implemented, plus a few new ones.
I don't know... it lacks contrast. I first thought it got the iron curtain effecting it.
Its a nice idea though. RA needs a few real units (reallity based) to get that Cold War feeling taken a step further. Perhaps someone could add a scout vehicle for the Soviets, since it is what they actually lack along with an AA vehicle.
maybe the ZSU-23-4 or ZSU-57-2
