The Total War series is just fantastic. The vast majority of strategy games almost always consist of some variation of a zerg rush. Be it rushing to capture strategic points to gain resources (Dawn of War) or gathering them up fast enough (Starcraft), most of the time if you're fast enough clicking you can win. Total War isn't like that at all; it actually requires skill to beat. As I've done loads of times, if you do things right you can beat hordes of enemies with just a handful of troops. It actually puts strategy into the RTS genre.
