The most prolific hybrid strategy series is Total War (Creative Assembly, 2000), which has seen 15 entries including expansion packs as of November 2010. Featured in Guinness World Records Gamers Edition 2011

Hybrid strategy games, exemplified by the Total War series combine the thrill of real-time battles with turn-based empire building, employing the "4X" gameplay (explore, expand, exploit, exterminate) that was made famous by the likes of Sid Meier's Civilization (Microprose, 1991).
