Metroid had everything, password system, lots of different worlds and secrets, awesome weapons...

User Rating: 9.2 | Metroid NES
This is the first game I've ever played, when I first saw it I was amazed. The character had fluid movement, weapons upgrade, missiles, huge levels, nice bosses, and the final battle was superb. I spent many hours playing this game, to the point of closing my eyes and seeing Samus shooting around. The password system revolutionized the game industry because you could stop at one point and then go on from there with a password. Who can remember those battles against Ridley, or Craig, or the weapons upgrades, like the ice bullets, the space jump, the different suits. This game is a must for any gamer that may want to take a look at how a game is not defined by its graphics, but by great gameplay.
