Commandos Saga

of course! Commandos is an epic game!!!

Its an awesome game. The commandos 2 is the better of all three games.
For commandos 1 you need to run a fix to prevent high speed on the game. And i've had a hard time making commandos 2 work with a friend on LAN.

I played and enjoyed them when they were first released, but not sure I could go back to them at this point. While their genre ages a little more gracefully than, say, FPS there are just better tactical games released more recently. Check out Warhammer 40,000: Dawn of War II, or if you don't mind turn based then XCOM Enemy Unknown. For the price though... hard to complain.
