The SEGA Master System was SEGA's answer to the NES. It featured games that were infinitely less popular than those on the NES (with a few exceptions, of course... the most prominent being "Ghouls N Ghosts"). I recall the gamepad being punishing during gameplay as it allowed strictly four directional movements as opposed to the NES which allowed eight. (Correction: the NES controller was limited to traditional 4 way movements. The Sega Master System implemented a much more comfortable 8 way D-pad). An interesting fact is that Sega Master System controllers could also plug directly into an Atari 2600 console.
