Okay, this is another idea I've been sitting on about a sequel to Phantom Hourglass. It isn't as developed as my other idea, Surreal Stretch, but I still think it's alright.
The game is called 'The Legend Of Zelda: Spectrum Trial'.
The game takes place an unknown amount of time after Phantom Hourglass. It starts with Link sailing on a ship, Tetra and crew too, almost identical to the beginning of Phantom Hourglass. But out of nowhere, Link is grabbed away from the ship by a strange force, a multicoloured portal.
Link awakens, in a Temple that appears to break the boundaries of conventional structure. Think of all those optical illusions you've seen in which there are stairs on the ceiling and everything seems to lead into each other in a nonsensical manner. Yeah, like that.
In this room are seven people.
Jala, the 'Hero Of Flames', saviour of the land of Ambrell not long ago by using a fabled wand that controls heat. She wears a red robe, with large boots and unimaginable amounts of jewelry. Her weapon of choice is a mace.
Daun, the 'Hero Of Weather', saviour of the land of Tenriss not long ago by using a fabled wand that controls rain/sun/clouds. He wears peasant clothes in an orange colour, with sandals and a funny looking sailor hat. His weapon of choice is an axe.
Pire, the 'Hero Of Light', saviour of the land of Kyojin not long ago by using a fabled wand that controls Light and darkness. He wears a shimmering gold plated suit, with a streak of Silver running down his torso. His weapon of choice is a rapier.
Link, the 'Hero Of Winds', saviour of the land of Hyrule not long ago by using a fabled wand that controls the wind. He wears a green tunic with a green matching hat. His weapon of choice is a generic sword (as always).
Clik, the 'Hero Of Water', saviour of the land of Drohht not long ago by using a fabled wand that controls the waves. She wears a blue kimono. Her weapon of choice is a katana.
Yuan, the 'Hero Of Illusion', saviour of the land of Kraden not long ago by using a fabled wand that controls peoples vision and image. He wears an indigo set of clothes similar to those that Linebeck wears. His weapon of choice is a trident.
Slet, the 'Hero Of Entropy', saviour of the land of Quaddi not long ago by using a fabled wand that controls the passage of time (only forward, mind you). He wears a Violet robe with a cape and a helmet. His weapon of choice is a whip.

Of course, none of this is revealed straight away.
As the seven of them stand in the room, puzzled, a shadowy figure rises from the middle of the room, similar in appearance to Phantom Ganon, only much more fluent and graceful.
This figure, Motral, tells the 'team' that they spend too much time saving other peoples lives and that they don't appreciate their own lives, even after risking it to save their respective lands.
Thus, he traps them in a trial on the island of Piron.
Each of the heroes' right hand starts to spasm and slowly morph into a strange looking mechanical hand, powered by cogs and clockwork. It is called the Curse of the Spectrum. Each of them are dressed in their respective colour of the rainbow; red, orange, yellow, green, blue, indigo and violet (Link, being dressed in green, is the middle colour of the rainbow).
Each person can use their Spectrum Hand to their advantage - they can change the colour of something by shooting a harmless orb at it. Link, then, can change things green. By changing the colour of something, it changes its behaviour. For example, by turning a rock green, it behaves like a tile of grass allowing you to walk over it. By changing a tile of lava into blue, it would behave like water. By turning an object into the colour of the floor tiling below it, it behaves like flooring and stops being solid. I could go into more detail, but I'd be here all day. Red means fire, Orange means soft/Sunlight, yellow means light, Green means nature, Blue means water, Indigo means Illusion and Violet means Swamp. There are limits as to what is affected by colour change, though.
The mysterious spirit sets them off on the 'Spectrum Trial'; they must work together to find the seven Shards of the Spectrum Lens. By doing so, they can use its power to return to their own land. However, as well as using their abilities in tandem, they must put their own lives ahead of others because only one person can leave the island. This means that even if someone seems like they're helping you out, you might find that they turn against you. By defeating someone who turns against you, you gain their colour power as well as keeping your own.
Thus, normal Zelda questing occurs as normal. For each dungeon, you must first (as with every Zelda) do a side-quest to gain entrance. However, each of the first six side-quests involves being helped by the other heroes, until they turn against you, at which point you must take their power and use it in the dungeon. The seventh dungeon involves all of the colours.
The eighth dugneon takes place in the original temple that you started in. You get mugged at the start by the other heroes, of your powers and your seven shards of the Spectrum Lens. You then slowly make them back up over the course of the dungeon.
At the end of it, Link gives the pieces to Motril. He then reveals that he too was playing in the Trial, and that the trial was set up by the Gods to see who is a truly worthy hero. He, however, arrived first, and, being manipulating as he is, posed as the Game Master so as to get the other contestants to play the game for him. The other contestants, realising their mistakes, chase Motril to the ninth dungeon (where the lens is to be placed), a generic tower on a mountain (who'd have thought?). There, Link returns the respective powers to each Contestant. The Ninth dungeon involves switching between all nine contestants (Like with Gongoron in
PH) to solve all of the puzzles. For the final battle, there are seven short segments, each fought by a different contestant (Link being the last).
Upon defeating him, the contestants, having become close friends, are uncertain as to what to do now. They universally agree that Link, being the true hero, should leave the island, but he decides against it, being a true hero. The game ends with the Contestants arguing who deserves to go home most, when the Goddesses, seeing Link as the most deserving, transport him home anyway.

It's a work in progress, but the way I see it, it would serve to provide both an interesting single-player AND multiplayer-mode. The mechanic of stealing peoples Spectrum Powers could translate well to a 4-player game. I'm not sure why the Goddesses would pull such a stunt, so that's a big problem, but I'll work something out.
Willing to accept criticism. I only thought of this earlier today, so it doesn't have much depth as of yet.
Discuss.
