Empire Earth is awesome, and Starcraft 2 should adopt many of the units from the futuristic era. I can't find the cd tho, and havent played for a while. They should use the Cybers tho! And the idea of planes that cant stay in the air forever, and have to refuel and rearm! And maybe a huge awesome looking nuclear explosion like the Titan! And last but not least, they should make space faring units, that can't be attacked by normal ground units, and can attack a huge area! Also, the upgrades for all units is good!
