@Robo . i noticed apart from halo wars you weren't big on the genre , Age of Empires 2 :Age of Kings is a good one , or if you like Warhammer 40000 then the Dawn of War series is great but if a more squad based game play with out the base building / rushing seems more your style Dawn of War 2 could be your game and lastly World in Conflict
