Well IMHO there are some great titles missing
at least on the 1st,2nd post
RTS (War)
Men of War Series: This one is not your like other RTS, here you have to control every unit, every unit has its own inventory, jeep, tanks to drive etc. Its having very steep learning curve but if you cross that you will love it, I think there are 3 expansion for men of war
Difficulty: 8/10

Theater of War: Again from the same company(1c), this time more focused on vehicles

Company of Heroes: Really great game Gameplay is nearly same as MOW series but a lot easier and fun to play, heh not so frustrating as MOW

World In Conflict: Most visually appealing game in RTS history, you should not miss it, again no base building in this one either.

Check out Ground control 2 as well, it was really impressive in visuals and was ahead of time.
