I don’t know how I find these random things, but I stumbled upon Chris Hazard and Ky Kimport’s take on what a Tolkien RPG would look like in the hands of Squaresoft.

In response, I would say that:

• You get your airship from the Shipwright Círdan, who happens to prefer being called Cid. He will also give you Narya, the Ring of Fire, but only if you have Gandalf in your party.
• The final battle sequence will actually consist of destroying Sauron in the Third Age, who takes the form of the Eye. The Nazgûl back him up. Then you travel back in time to the end of the Second Age to defeat Sauron in the Battle of the Last Alliance. After that, you go back earlier in the Second Age where you have to defeat him in Númenor before it sinks under the ocean (yes there is a time limit!). Finally, you go all the way back to the First Age to defeat Sauron, who is teamed up with Thuringwethil the Vampire and Draugluin the Werewolf. Once Sauron is utterly defeated, you are then faced with fighting Glaurung, the father of dragons, Gothmog the Lord of the Balrogs, and finally, Morgoth, the Dark Lord who has about a trillion hit points, and can only be physically damaged by the swords Ringil, Anglachel (but you want to upgrade it to Gurthang when you get a chance), or Anguirel, and also the knife Angrist (although it has to be reforged) You can also use Radagast’s summoning abilities (only the Eagle summon works) or hopefully you have at least one Silmaril, which, like Materia, can be inset into your weapons and give it Morgoth-damaging capabilities.
• Depending on whether or not you look in Galadriel’s Mirror while in Lothlórien, you can unlock the Scouring of the Shire final subquest. This will allow you to keep playing even after you defeat Sauron and Morgoth and unlock Elrond, Galadriel, and Círdan as playable characters. Upon completing this mission, you can unlock the best ending.
• Among the optional characters you can fight (all of whom have maybe at least a quadrillion hit points each) are the twin Blue Wizards who turned evil, Alatar and Pallando, and the penultimate optional battle is Ungoliant who has an octillion hit points, has six different forms, and has the attack “Withering of the Two Trees” which kills all the characters of your party except one, regardless of how many hit points you have, what armor you have equipped, or what magical protection you’ve cast.
• The ultimate optional battle pits you against Neo-Morgoth, who is partly cybernetic, and who has sexdicillion hit points and will take literally 24 hours to beat (not counting breaks) and who will be far more difficult than the actual final battle of the game. On the upside, you should have the Elven Lords at this point, who can all inflict massive amounts of damage thanks to the Rings of Power
• Various optional subquests include the reconquest of Moria, the cleansing of the Barrow Downs, the Colosseum in Umbar, lifting Numenór back out of the ocean, lifting Beleriand back out of the ocean, restoring the Two Trees, finding and clearing Angband, and finding and clearing Utumno
• Valinor becomes accessible if you have a Silmaril
• Like other Final Fantasy games, you can gather certain talismans to summon Elf Lords, Maiar, and Valar to fight for you temporarily.
• Limit breaks/ultimate attacks:
  • Samwise: precision apple throw (instantly fatal), elven-lord charge (attacks multiple foes at once)
  • Frodo: the phial of Galadriel (holy damage to all foes)
  • Merry: the horn of Rohan (summons the Rohirrim to deal damage to all your foes)
  • Pippin: Bullroarer’s attack (instant death by decapitation, leading to a hole-in-one)
  • Aragorn: Flame of the West (fire attack to all foes), Wings of Thorongil (wind attack to all foes), The Light of the Elfstone (holy attack to all foes)
  • Gimli: Axes of Khazad (damage to multiple foes), Durin’s Hammer (massive damage to a single foe)
  • Gandalf: The Flame of Anor (massive holy damage), the Lightning of the Maiar (massive electrical damage), the Hand of the Valar (only available for Gandalf the White, dealing incredibly massive amounts of holy damage)
