Age of Empires

A computer game which requires alot of strategy and takes place in the early "ADs". You can play as various civilizations and your goal is to rise to become the most powerful one (or last surviving) in the map. Online play is also featured. The expansion (AoE: Conquerors) features more civilizations and new units (military personal / technologies). This game makes for a great alternative to masturbation, or can serve as a "timetaker" while your downloads complete.
