Sugest me a good Strategy game.

On PC get Anno 2070, Company of heroes 2 and Shogun 2 Total War Gold. Get Rome 2 when the game also receives a Gold edition within a year or so. 

If you don't mind even older games you should definitely play Age of Mythology which for me is timeless. Because nearly 12 years after release I still like to play the game. Medieval 2 Total War has some of the best mods ever created like Third Age Total War(Lord of the Rings overhaul). Command and Conquer Generals and C&C3 I consider also timeless just like the first company of heroes.
