Kid Icarus is an action platform video game for the Family Computer Disk System in Japan and the Nintendo Entertainment System in Europe and North America. The plot of Kid Icarus revolves around protagonist Pit’s quest for three sacred treasures, which he must equip to rescue the Grecian fantasy world Angel Land and its ruler, the goddess Palutena. The player controls Pit through platform areas while fighting monsters and collecting items. Their objective is to reach the end of the levels, and to find and defeat boss monsters that guard the three treasures.

One of the defining characteristics of the Gradius series is the use of a “power meter.” The power meter is powered by a power-up item, whose purpose, when collected, is to move a highlight to the next power-up on the power meter. When a power-up that the player wants becomes highlighted, he or she may activate it, also causing the highlight to reset.

Ghosts ‘n Goblins is a platform game where the player controls a knight, named Sir Arthur, who must defeat zombies, ogres, demons, cyclops, dragons and other monsters in order to rescue Princess Prin Prin, who has been kidnapped by Satan, king of Demon World. Along the way the player can pick up new weapons, bonuses and extra suits of armor that can help in this task. The game is often considered very difficult by arcade standards and is commonly regarded as one of the most difficult games ever released. The game is considered by Gametrailers.com to be the world’s second most difficult game ever made. The player can only be hit twice before losing a life (the first hit takes away Arthur’s armor, and the player must continue on in his underwear until completing the level, or finding replacement armor). If the player loses a life, he is returned to the start of the level, or the halfway point if he has managed to get that far. Furthermore, each life can only last a certain length of time (generally around three minutes), the clock being reset at the start of a level. If the clock does run out, the player instantly loses that life. After defeating the final boss, but only with the cross weapon (if the player does not have the cross weapon, they will be prompted that it is needed to defeat the boss and restart at the beginning of level 5 and must repeat round 5 and 6 again regardless if the weapon is obtained immediately or not) for the first time the player is informed that the battle was “a trap devised by Satan”. The player must then replay the entire game on a higher difficulty level to reach the genuine final battle.

The objective of Galaga is to score as many points as possible by destroying insect-like enemies. The player controls a starfighter that can move left and right along the bottom of the playfield. Enemies swarm in groups in a formation near the top of the screen, and then begin flying down toward the player, firing bombs at the fighter. The game ends when the player’s last fighter is lost, either by colliding with an enemy or one of its bullets, or by being captured. Galaga introduces a number of new features over its predecessor, Galaxian. Among these is the ability to fire more than one bullet at a time, a count of the player’s “hit/miss ratio” at the end of the game, and a bonus “Challenging Stage” that occurs every few levels, in which a series of enemies fly onto and out of the screen in set patterns without firing at the player’s ship or trying to crash into it. These stages award a large point bonus if the player manages to destroy every enemy. Another gameplay feature new to Galaga is the ability for enemies to capture the player’s fighter. While the player is in control of just one fighter, a “boss Galaga” (which takes two shots to kill) periodically attempts to capture the fighter using a tractor beam. If successful, the fighter joins the enemy formation. If the player has more lives remaining, play resumes with a new fighter. The captured fighter flies down with the enemy that captured it, firing upon the player just like normal enemies, and can be shot and destroyed. The player can free the fighter by destroying the boss Galaga while in flight, causing the captured fighter to link up with the player’s current fighter, doubling his or her firepower but also making a target twice as large. Galaga has an exploitable bug that can cause the attackers to stop firing bullets at the player, due to a coding error. In addition, similar to the famous “Split-Screen bug” in Pac-Man, a bug exists in Galaga in which the game “rolls over” from Level 255 to Level 0. Depending on the difficulty setting of the machine, this can cause the game to stall, requiring that the machine be reset or power-cycled in order to start a new game.
