1. #10: Intellivision Soccer (1980, Mattel Electronics, Intellivision)
This is pretty much where it all started. Before the Intellivision console came along, most football games were derivative Pong rip-offs that consisted of a few bats on a monochrome 2D screen. Intellivision Soccer ushered in the 3D revolution - in an astonishing five colours. The isometric viewpoint and scrolling pitch would dominate sport games for years to come, everything from NBA Jam to Madden NFL owes it a huge debt.
