Nice article by Russell Adderson, which takes me back…
I'm aware of almost all of 'em, dabbled with a few, but the only ones I played fully were the Dark Reign titles. DR was my 3rd-fav RTS series back in the golden age, after the C&C universes and Total Annihilation.
One not in the article, and sadly very underappreciated imo, is:
Hegemony III: Clash of the Ancients on Steam
Command armies, manage resources, and build an empire in this real-time strategy wargame from Longbow Games. Will Rome fulfil its destiny to rule the ancient world or will history be rewritten to forge a new Etruscan, Gallic, or Greek hegemony!
How about you?
