As far as strategy games go, I grew up with Warcraft 1 and 2, Starcraft, and Command & Conquer.
Then as I got really good at Command & Conquer Generals, I discovered the badassery that is found in Warhammer 40K Dawn of War, and now I play Dark Crusade.
Recently somebody introduced me to the demo of Homeworld 2. The mechanics, visuals, and overall gameplay is slow, but brilliantly designed. I fucking love Homeworld 2's demo, and I'm thinking about buying it in it's entirety.
If I'm this impressed with Homeworld 2, what other game would I enjoy or should at least look into?
