I've got two suggestions for you.
First is Company of Heroes. I've played this for around 440 hours and I'm getting pretty damned good at it. If you're into RTS games that have many little skirmishes instead of massive scale battles, you'll love the game.
Second is Civ:IV. The games go so fricking in-depth it's AMAZING. It's a turn-based (sorta) RTS. More of a civilization builder game (as the name suggests).
