Super Hydlide

Super Hydlide is an action RPG for the Sega Genesis/Mega Drive. It was originally released in 1987 in Japan only under the title Hydlide 3: The Space Memories (ハイドライド３ 異次元の思い出) for the MSX, MSX2, and NEC PC-88. The game was developed by Hydlide series veterans T&E Soft and released on the Sega Mega Drive on October 6, 1989, in Japan, early 1990 in the United States, and 1991 in Europe. This remake evidences substantial graphical upgrades to the original Hydlide 3, though the gameplay remains largely identical. Before its release, it was called Hollo Fighter in some Sega advertising material and was one of the first third party published titles to be released in the U.S, the other being Air Diver.

A slightly simplified port was released for the Nintendo Famicom under the altered title '''Hydlide 3: Visitors from the Dark (ハイドライド3 闇からの訪問者). A special version of the game, referred to as Hydlide 3SV, was released for the NEC PC-98 and the Sharp X68000. The special version contained new visual scenes, new maps, and new characters.

The game incorporates a 'good/evil character' morality/alignment system. Like its predecessor Hydlide II: Shine of Darkness (1985), the player has a morality meter that can be aligned with either Justice, Normal, or Evil. The game has both good and evil monsters. Evil monsters attack the player character on sight, while good monsters only attack if the player character attacks them first. Killing any monster, good or evil, results in a reward of experience points, money, and occasionally a piece of equipment. However, if the player kills a good monster, points are lost from a statistic called "MF" (Moral Fiber). If the player's MF stat drops to zero, frequent traps will appear across the world. If the player manages to keep it over 100, rewards appear in the form of random items found around Fairyland. Unlike Hydlide II, however, the morality meter no longer affects the way in which the townsfolk react to the player.

The game also features an in-game clock setting day-night cycles, where the character must eat two times a day and sleep regularly. If the characters stay up late or fail to eat regularly, their HP and attack power gradually drop. Every item in the game (including money) has weight. If the total weight of items the player character carries exceeds their "Load Capacity" (LC), they will move slowly. The game uses cut scenes for its opening and ending sequences, a combat system similar to Ys, a choice between four distinct character classes, and a wide variety of equipment and spells.
