My Favorites:

Space Empires 4 Gold is very good.

The War Engine I have enjoyed a lot (actually, the earlier Version - Armies of Armageddon, and some mods).

I found the Coliseum demo dangerously entrancing. I may buy it the next time I have to take a plane trip with a laptop that has a good battery. It's a very different sort of game, though - some people will like it a lot (statistics, gambling, hidden character attributes), and others might not see anything in it (no animation and not much control over the fights), so try the demo if it sounds interesting.

The Combat Command 2 games (Danger Forward and Desert Rats) are good wargames at their level of scale and abstraction. Try the demos to see if they suit your tastes. I think the abstraction works well for just about everything except armor details (sadly, I'm an armor detail nut). I still had a lot of fun with them.

Remote Assault has a very challenging AI, it seemed to me. The style of the setting (futuristic robotic pseudo-modern forces) was the only thing that kept it from becoming a personal favorite. Maybe that and getting slaughtered by the AI over and over while trying to learn the effective ways to use the unit types.
