The most popular top down games

Top down games were very popular in the 80s and the 90s, when graphic cards were not capable of supporting 3D, and even when 3D started to become popular, 2D games continued to be easier to develop, at least in the infancy of 3D gaming. 2D game offered the player a viewpoint that helped keeping things easily under control (think about top down party-based RPGs or hex-based strategy games).
