69. M.C. Kids (Virgin Games, 1992)
M.C. Kids is a game that's frequently overlooked, but I can't give people too much crap for that. Between its late release and being an advergame for McDonalds, it's one that few people paid any mind to in the 90s and most who learned of it later dismiss immediately. However, those who gave it a chance found a highly polished and fun platformer that takes several cues from the Super Mario Bros series. One can pick up and throw blocks to defeat enemies or weigh themselves down to spring higher on springs, flip their own gravity and traverse stages upside-down, and of course find a huge plethora of secrets and bonuses in each level. Even the visual style is similar, with some smoothly animated characters and detailed sprites. Virgin would go on to make several highly-acclaimed games (most notably Aladdin on the Sega Genesis), but M.C. Kids never quite got its due.
68. Double Dragon (Technos, 1988)
Definitely one of the most popular beat-em-up franchises of the 80s, Double Dragon was nothing short of an institution at the time. It had several sequels and home ports to just about every platform imaginable, a live action movie and even a cartoon series. Probably the most well-known and successful port of the time was the NES version, which was a very different beast from the arcade (and pretty much every other home port, for that matter). Much different levels and a unique leveling system tied to unlocking new moves made it a distinct experience, as did a two-player versus mode well before the age of Street Fighter II. It was also notoriously buggy and lacked a two-player mode owning to the developers' inexperience with the hardware, but that didn't hamper its enjoyment factor at all. A great version of a classic.
67. Mega Man (Capcom, 1987)
Mega Man is probably better remembered today for its infamously terrible box art than for the game itself, but it shouldn't be; it kicked off a fantastic series of action-platformers and was a fine title in its own right. It laid the groundwork for the series, featuring a protagonist who could defeat bosses and then take their weapons for himself, not only making later levels easier to deal with, but making him better prepared to take out other bosses who were weak against that particular weapon. Bombs, fireballs, whirling scissors, lightning, an ice beam that could freeze enemies in place and, perhaps coolest of all, the ability to pick up and throw blocks bigger than himself to clobber foes. It wasn't the most refined game ever - some bosses were monstrously difficult and it lacked several later series refinements like a password system or post-hit immunity protecting from spikes - but it was a great game anyway.
A relatively early Nintendo title that didn't get a whole lot of attention at the time of its release despite combining elements of several other popular games. It had the dungeon-crawling element of Zelda, the platforming of Mario and the plethora of hidden secrets and tricks akin to Metroid, and even a side-scrolling shooting stage akin to Gradius or Life Force. However, it was hampered by a high level of difficulty overall and some rather frustrating elements to its design (Particularly the notorious eggplant wizards and Pluton flies, which turn you into a harmless eggplant until you visit a hospital and steal your items respectively). Still, those who could adapt found a worthy adventure to undertake, with multiple endings endings giving it some extra challenge and replay value. It may not be the most beloved Nintendo IP out there, but Kid Icarus is still a game worth checking out.
64. Dr. Mario (Nintendo, 1988)

63. Castlevania II: Simon's Quest (Konami, 1988)
The sequel to the original classic Castlevania, which, like Zelda II, tried to change up its action-driven format into something more akin to an RPG. Also like Zelda II, it wasn't quite as well-received by fans for a number of reasons, chief among them being its lackluster translation that made a number of essential clues much more difficult to decipher. Still, those who could persevere through that found a game with a lot to offer- the same high-quality presentation that became a series trademark, a number of dungeons to explore, a couple of big bosses to fight, and a lot of creative upgrades and sub-weapons to unlock throughout. It may not be regarded as one of the franchise's best by many of its fans, but it's certainly worth a look for fans of action-adventure titles.
(Fans of ROM hacks may also want to check out "Castlevania II Redaction", which addresses several criticized elements of the game - notably speeding up the text and day/night transitions and rewriting much of the dialog to provide useful clues.)
One of many Disney-licensed platformers on the NES by Capcom, and one I rented many times as a kid because it was just a fun and addicting game. Capcom's strong level design shines through here, delivering some creative stages like a kitchen (with faucets you have to turn off to pass through safely), a toy factory and treetops with attacking flying squirrels. Some solid music and visuals also complete the package, as does a two-player simultaneous play option that makes for a fun romp, even if you tend to get in each other's way more than help. The game is ultimately fairly short and not especially difficult to complete, but I still pop it in and play it to this day because it's a nostalgic favorite and a pretty damn fun platformer.
Named "Guevara" in Japan and appropriately starring Che Guevara and Fidel Castro as they waged a two-man battle to liberate Cuba, SNK (quite wisely) decided to remove all real-life references when they brought the game to America in both arcade and NES form. The arcade version of the game featured a rotary joystick that allowed the player to move in one direction and fire in another at the same time, something they attempted to recreate in the first two Ikari Warriors games on NES with pretty terrible results. Thankfully, the port of Guerilla War abandons this idea and just has four-directional movement and firing, as well as considerably quicker gameplay speed. It's great, fast-paced fun, especially with two players blowing up everything in their path.
