Vanguard/YMMV


 * Fair for Its Day: The Atari 2600 version of the game, assuming you're used to modern-day graphics. Sure, it had clunkier graphics and lack of speech due to technical limitations, but those were expected for an Atari 2600 port. Its controls were also highly customizable, with four different options, though two are somewhat unintuitive (because they require that you press the fire button to stop shooting).
