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.

68. Double Dragon (Technos, 1988)
67. Mega Man (Capcom, 1987)
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.
66. Battle of Olympus (Infinity, 1989)
65. Cyber Stadium Series: Base Wars (Konami, 1991)
64. Zoda's Revenge: Startropics II (Nintendo, 1994)
One of the very last games officially released for the NES, and it was quite a good one. A followup to Startropics - a game curiously programmed by a Japanese development team but only ever released in the west - Startropics 2 featured tighter controls, crisper graphics and a new plot involving Mike travelling through time searching for the seven magical Tetrads. Oh yes, Nintendo had the Tetris license at the time and they wouldn't let you forget it.
Another welcome change was the general softening of the difficulty curve - while still very challenging, cheap shots that took off a third of your health bar were now a thing of the past, and making contact with the bosses wasn't an instant death sentence - you simply lost a large chunk of your health. Just a touch more of the problem-solving aspect and solid narrative of the original and this may very well have surpassed it!
