57. Super C (Konami, 1990)
56. Summer Carnival '92: Recca (Naxatsoft, 1992)
55. Mega Man 6 (Capcom, 1993)
Considered one of the weaker entries on the platform by a lot of fans, Mega Man 6 certainly showed signs of being rushed. It came out late in the system's life and Nintendo, in the role of producing this title, was clearly banking on it being a send-off game for the soon-to-be-retired NES; the level quality and challenge definitely suffered as a result. However, it did also have some unique quirks to set it apart. Instead of calling in Rush, you now morph with him into two forms - Rush Power (which can smash through walls and deal damage with short-ranged punches) and Rush Jet (serving as a jetpack that allows flight for short distances). It also had some great music as per series norm, proving that if nothing else, Capcom was striving to make it memorable if not one of the best. It's a ton of fun to play in spite of its faults, and hey, classic Mega Man at his weakest is still better than most game franchises at their best.
54. Willow (Capcom, 1989)
51. Dragon Warrior III (Chunsoft, 1992)
Probably the premier JRPG series, the first game was hugely popular in its time and the franchise has continued to be an unstoppable force in Japan, with most stores even refusing to sell the games on weekdays so kids don't skip class to go buy them. Among them, Dragon Quest III continues to be regarded as the best of the NES era, and for good reason - it keeps the defining charm and simplicity of the series while working in a Final Fantasy style customization element, letting you pick from several classes to tweak the game's difficulty to your liking. About halfway through the game you can even change their class, letting them carry over some stats from their original jobs while branching out into an other discipline to become even more powerful. Story wise it also serves as a clever prequel to the first two games, with a lot of events that are only told in legend there becoming reality as you venture across the land and conquer the evils in it. Like Final Fantasy 1, though,you may want to play one of the remakes over the original nowadays, as they all have various balance tweaks and added content like new weapons and classes.
Another very overlooked game, though I can't blame people for that because the game only saw an extremely limited release in exactly two regions - Japan and Scandinavia - in the twilight days of the system. It's a real shame it didn't get a wider release, too, as this may just be the most impressive game on the system on a technical level. Not only were the sights and sounds top notch, but the programming here is superb - objects actually actually slide down slopes and ricochet off objects realistically and enemies show a modicum of artificial intelligence, backstepping to evade your attacks and attempting to trap you in tight spaces when given half a chance. It's also surprisingly tough for such a cutesy-looking game, requiring you to master the finer points of the physics and your bouncing star weapon (which can also double as a platform when jumped upon) in order to collect all the hidden treasures and reach the best ending. Oh, and did I mention you can't use any continues either? ...Yeah, if you want that ending, you're going to WORK for it!
49. Arkanoid (Taito, 1986)
Another game known for its wacky plot, introducing a wireframe Moai head named "DOH" pulling Earth's space forces into a pocket dimension or some such nonsense. It's all a bit arbitrary, though, since this never comes into play until the final stage of the game; until then, it's all about smashing bricks with a ball and paddle in a game heavily inspired by Breakout. The gimmick that sets it apart, though, is its powerup system - broken bricks drop icons that enlarge your paddle's size, give you multiple balls to break bricks with, allow you to "catch" the ball and release it at a more favorable angle, and my favorite, the ability to shoot lasers from your paddle to break bricks and destroy enemies. The game even came packaged with a custom-made controller that featured an analog knob, which made the gameplay much more smooth than with a standard controller. It's a bit of a scarce collector's item these days, but if you can track one down, give it a go with this game. It will not disappoint!
