Someone asked about Civilization 5 recently and apparently that's not a proper RTS.
Mentioning RTS only made me want to play one again. A few years ago I enjoyed a C&C game on my dad's PC.
What game lets me build an army and then send that army into battle or to capture/protect an area?
I like the idea of developing a force, educating and training them, then gathering resources and/or taking other civilizations' land - or becoming their ally; slowly taking over the world.
I've been looking at Planetary Annihilation, but I doubt it has replayability.
Right now I'm downloading the C&C Red Alert 3 demo.
