in terms of aesthetic value, super mario bros. (NES) was pretty impressive, lol.
i was used to shyt on the atari, so when SMB hit the scene, the colors, variety of levels and tight controls were at another level ( for most kids) at the time.
mortal combat, killer instinct, virtua fighter, resident evil, tekken (with the awesome cut scenes) and shenmue, were all amazing to me, when they came out respectively.
