Sins of a Solar Empire seems certainly a superb game in videos, but was looking for something with the features described. I wanted to return to RTS when I saw a building construction in Settlers, haha! I want to feel again the sensation of design my base/town, with variety of units and tactical maps. Any modern RTS similar to Age of Mythology or Starcraft.

It might help to mention that the RTS I most enjoyed in my childhood probably was Total Annihilation: Kingdoms, the only "flaw" to me was the construction method, I prefer the traditional AoE/Starcraft build system...

I already have Starcraft 2, which I love (the only RTS I've played the last years), I don't want to buy its 2 expansions (I will buy the three together at the same time in the "gold pack" or whatever they'll call it). So meanwhile I want to return to RTS genera in a similar game, please recommend me your favorites considering the following features:

-Modern graphics (equal or better than Starcraft 2).
-Building construction style (I like to choose the location of buildings as Age of Empires).
-Selection and command of troops (micromanagement of combats).
-Single player offline mode (nothing like AoE Online).
-Fantasy background (modern, medieval or futuristic but not "only humans").

I have in mind Warhammer 2, Universe at War, Worldsifht, or King Arthur 2; but I don't know if they meet my requirements, but some of them does not seem to have building constructions in place, I don't know so I'm asking. Thanks!
