I seem to have misunderstood the task "do some worldbuilding for my DnD world" because im building my world using the Final Fantasy 1 (1990) map editor
have you ever felt that FFI is too easy of a game?
would you like to make it easier? what about harder? want to remove the world map? what about completely redesigning the world map? what about changing entrances around, moving from Gaia to Mt. Gulg in a single doorway?
then you should try the Final Fantasy Randomizer!
the FFI randomizer will completely restructure the classic NES RPG to however you wish to play it, completely new ways to play it in any way you can think of.
there's a selection of randomization preset options, between "beginner" selections to make the randomization more easy if you're newer to the game, to "intermediate/expert" options if you're more familiar with the world of FFI.
Improved Vanilla and Beginner are the best selections for starting the randomizer. Beginner works by changing the game just enough to get you to be more familiar with how the randomizer works and functions, while IV fixes bugs that were present in the original, as well as adding quality of life fixes present in the later FF games.
Procedurally Generated Overworld is just what it sounds like - your stock-standard FFI experience, but the world has been completely randomized, areas will never be in the same spot twice.
Floaterless removes the airship, adding extra docks to the upper continent near most noteworthy areas.
Oops, All Loose! and Shard Hunt add key items and completion objectives into the item pool, chests will now carry items you need to finish the game! Shards themselves are the objective rather than the Orbs you need to collect to reach the Temple of Fiends.
Entrance and Floor Shuffle is exactly that. Doors will never lead to their original locations, you can go from one area to another without knowing where you go until its too late.
the beginner options are all simpler, they make the game just tricky enough to add a new challenge, and improve EXP and gold gain accordingly! but that's not all, the intermediate/expert options make the game all the more confusing.
Chaos Rush unlocks the Temple of Fiends immediately. your classes are pre-selected, and all methods of travel and upgrades unlocked. you level up much faster to compensate the end of the game being thrust upon you. how fast can you beat Chaos?
Deep Dungeon turns the game into a dungeon crawler. Coneria Castle turns into a 52 floor dungeon with Chaos waiting for you at the bottom, and different towns peppering the floors to make your trek a bit easier.
Free Enterprise models the experience after FF4: Free Enterprise. you start with 2 party members, and you get the opportunity to recruit more as the story progresses. there's quite a lot to this one!
Over Randomizer changes everything! new weapons, spells, enemies, bosses. anything that can be changed will be.
Hidden Chaos is my personal favorite. where is Chaos? who knows! you have to find him, trapped in a random chest somewhere in the entirety of the world!
Lich's Revenge changes the story, with the Fiend of Earth taking over, rather than Garland. all of humanity has fallen under the necromancer's plague of death, attacking you once their job has been done. bikke will strike as soon as you recieve his ship, as will the dwarves under mt. duergar, and even the king of dragons will challenge you once you prove your might as champions.
NOverworld is the final preset - not as a final challenge, but probably the hardest in my eyes. every village, castle, and dungeon is connected via staircase. the challenge comes from memory, and exploring every nook and cranny of the world to find out where the hell you need to go to get to Mirage Tower.
overall? FFIR is an incredible experience. all the presets change the game in a fun way, making everything so much more than the original game. not to say the original FFI is a bad game, it's a blast! but you should take some time to try FFIR, experiment on some of the extra options as well!
transmooglification? custom sprites? melmond zozo-fication? random vampire attack? major item shuffling? the world is yours to randomize - play FF1R with your own legally acquired ROM.
