Recommend me some good RTS games.

I loved Dark Reign before my old copy was stolen.

Also, Herzog Zwei is the most awesome RTS in existence. :D

Go for Red Alert 3 or Dawn of war (the series)

RTS games bore me, come back to me when you need FPS, MMOs or MMOFPS games

Supreme commander, don't get 2 get the original gold edition, 2 is a toned down arcade version of the first

StarCraft 2 is the only real RTS...

Total Annihilation

Or Supreme Commander if it must be Steam.

Supreme Commander 2

I'm just gonna leave this you don't need anything else

Check out Spellforce, Spellforce 2 and the expansions. It is not a pure RTS but a hybrid of RTS and RPG.

Earth 2160 but it's not steam.
