The 7th Saga

The 7th Saga is a turn-based role-playing video game developed by Produce! and published by Enix for the Super Nintendo Entertainment System in 1993. The game made innovative use of a radar system during gameplay. It featured 7 playable characters of various types including humans, an elf, a dwarf, robots, a demon, and an alien. Each character has unique items and spells. 
The game Mystic Ark was planned to be marketed as a sequel to 7th Saga in North America, but the game was only ever released in Japan.
Gameplay.
The player chooses one of seven playable characters, all of whom separately embark on a quest to locate seven magical runes. As the player progresses through the game from one town to the next, they encounter the other six characters on multiple occasions. The player may partner with one of the other playable characters to fight as a team, and they may also fight against other playable characters for the runes.
Notable unique innovations include the use of a crystal ball "radar" in the game's HUD that allows players to see enemies approaching their character in dungeons and in the overworld. This means that combat is not totally random, as players may theoretically avoid enemies (although enemies are numerous and move extremely quickly and randomly, making combat difficult to avoid). The game also uses Mode 7 graphic effects to create the transition between exploration screen and battle screen.
There are three modes of play: safe area, enemy-infested area, and in-battle. When the characters are in a safe area, usually in a city, they can walk around as long as they want. The player can talk to non-player characters, buy and sell items, search for hidden items, and rest at an inn. Also, the main character may duel other characters, or even convince one to assist in the search for the runes.
When the player is in an enemy-infested area, the Magic Crystal item in the top-left appears. That crystal shows the player in the center, and the relative locations of nearby enemies, cities, dungeons, and runes. If a white dot reaches the center, i.e. the location of the main characters, a battle will break out. The player must move around quickly while grabbing chests and finding the way, since the enemies are always getting closer.
Battles in the game are turn-based. When the player character is in battle, the perspective shows the character and ally, if any, from behind looking at one to three enemies. Players then select an action and take turns with the enemy and ally. The player can attack, defend, cast a spell, use an item, or run. If the player wins, their characters get experience points, gold, and occasionally items. If they lose, half of their money will be gone. If the player loses to one of the other main characters, their rune(s) will be taken by that character. Gaining experience results in attaining levels which improve a character's skill. Buying better weapons and armor with the money improves a character's fighting ability.
The game is particularly known for its unforgiving difficulty due to balance changes made in its localization. Enemies were given much higher stats, and the player character's stat increases were reduced (the other playable characters retain the original stat increases, so they will always surpass the player character's level).
Story.
The game takes place on a world called Ticondera. Five thousand years before the beginning of the story, a divine being named Saro defeated an evil entity named Gorsia with the power of seven runes. In the years since then, the runes have been scattered across the globe. Lemele (Remeer in the Japanese version), the son of Saro, was born 100 years before the beginning of the game, and became a hero when he defeated the demon Gariso. Now 100 years old, Lemele has become the benevolent and powerful ruler of the world.
The seven characters are recruited from various walks of life and corners of the globe by the elderly King Lemele. After 5 years of training at his palace, Lemele dispatches his seven apprentices in a quest for the seven runes. Each rune possesses a great power that can be used by the person who wields it. The one who collects all seven runes will become Lemele's heir. To find the runes, the king gives each character a Crystal Ball to assist them in their search.
Retrieving the runes means confronting the various powerful tyrants who have come to possess them, including wizards, kings, and dragons. The apprentices are also being hunted by a persistent bounty hunter named Pison (Python in the Japanese version), who has been hired by one of the apprentices to eliminate the rest (the identity of the "traitor" apprentice is randomized with each new game).
After defeating a resurrected Gariso and collecting all seven runes, the player is confronted by Lemele, who reveals that he is actually Gorsia. Gorsia traveled to the present from 5,000 years in the past, killed Lemele and took his identity, then recruited the seven apprentices to locate the runes for him. The power each rune contains is actually a trapped portion of Gorsia's power. Gorsia destroys the runes, re-absorbs his lost power, and zaps the player with lightning, sending them to a strange, unfamiliar world which turns out to be Ticondera 5,000 years in the past.
After passing through several towns, the player eventually ends up in the technologically advanced city of Melenam, which was originally explored as ruins by the player early in the game. Melenam is revealed to be the origin of the Tetsujin robots, and the player witnesses the destruction of the city at the hands of a rogue super-Tetsujin created by the city's scientists for the purposes of fighting Gorsia.
The player eventually learns that although Saro had recently defeated Gorsia, Gorsia has returned from the future and fatally wounded Saro. Saro's disciples give the player the seven runes, which the player uses to seal Gorsia's powers and eventually defeat the evil being. The dying Gorsia kills the player in one last act of revenge, but 4,900 years later Saro reincarnates the player's soul as a young baby and Saro's son: none other than Lemele.

Characters in "The 7th Saga" run along a continuum from predominantly physical-oriented to predominantly magical-oriented. They are, in that order:
Reception.
"The 7th Saga" received moderately positive reviews. Nightrunner of "GamePro" applauded the game's graphics, animation, music, sound effects, and non-linearity of the plot, and stated "the game's multiple characters and variable plot are innovative in many ways," but opined that "the frequent, simplistic combat does not live up to the rest of the game," and "the unrelenting combat and convoluted puzzles may drive away all but the most dedicated role-players." The reviewer added that "for all its originality in looks, sound, and premise, "Saga"'s gameplay is very reminiscent of [the likes of] "Phantasy Star"." Overall, they recommended the game to RPG players who "don't mind incessant combat".
Proposed sequel.
Enix planned to market the game "Mystic Ark" as a sequel to "The 7th Saga" in North America, under the title "7th Saga II". However, the game's localization was never completed, and it was released only in Japan under its original name.
