Also Battlezone 98, Sacrifice, and the Ground Control games is you like a little something different.

some of the less popular but (allegedly) okay RTS games:
Armies of Exigo
Kingdom Under Fire
LOTR Battle for Middle Earth 2 with the Witch King expansion
Turn based 4x goodness:
Eador Genesis
Andrew Lewis
The Warlords Battlecry series. 3 is probably the best.
Also the Spellforce games.

Oh yeah, Spellforce. I really liked 2. Didn't care much for 1 but apparently that is the more popular one.
