ability;
the Fleeting World!
production of ships are 25% increased, sight is +1
The full name would be better: "With This Ends the Fleeting World!"
Honestly, this UA feels like a variation on the much maligned American UA, albeit with a bonus to a way to produce the best way to fight AI on high levels. (Something I feel you might have picked for a reason.)
I feel that it's too basic and mediocre for a civ at this point. There's just so little versatility for that. And really, it doesn't really fit the name very well.
If it's a joke AFD civ as was suggested, I'd almost say it could draw from the Mass Effect Reaper civ, where they start with an overpowered unit and can't lose except by conquest. Only fitting for the emissary/avatar of Taisui Xingjun, god of calamity.
special building(Catfish "The Earth Liquefies into Mud!" i feel that land manipulation is a must.)
flood planes
workers can be used to turn tiles into flood plains(no tundra or snow)
You actually mean Marsh. Flood Plains are desert non-hills next to river.
Also the code savvy people can correct me if I'm wrong, but while you can change what kind of terrain a tile is during a game, there's no way to refresh the graphics, meaning it will retain the graphics of the original tile. This could be different with marsh, since it's removable like jungle and forest but I can't be sure.
The other issue is that this is a building for some reason, and its only purpose is to let workers turn tiles into one of the most useless terrain types in the game. Marsh is terrible unless you're the Dutch.
A better idea is to give the building a bonus to marsh tiles, since they're non-improvable and otherwise useless. Put the workers turning other land to marsh in the UA.
special unit
big fish replaces nuclear submarine can carry two additional missiles. can enter floodplains.
This is extremely lategame and not particularly viable unless you play on higher difficulties, where other units will have surpassed you in other victory categories far before you can get the subs, because you don't have a good UA and all your land is useless marsh. If you did actually make use of your slightly improved navy, you can win before the subs are relevant.
I'd suggest instead making the Giant Catfish a unique hero unit, like Tropico's El Presidente or Railgun's Mikasa Mikoto, where they upgrade throughout the tech tree. Have him behave as a combat unit as well as an Admiral, since he's obviously a fish and therefore more of a naval unit. (This will obviously mean you'll need actual coast and a coast bias.)
I'm not sure what I think of marshes-as-canals, but it's certainly an idea. Once again I'm not sure that's at all possible without something like those DDL mods, but it might be, there is that forts-as-canals mod on the workshop. Restricting it to a late game unit when you have a thing to let workers (I assume this ability would be somewhat before atomic era) make marsh is kinda poorly planned.
might need to Hong Meiling it as well even though SDM is already in the game.
This would actually be good to paired up with a joke AFD Catfish, since Meiling was the one to defeat him, and she's not exactly material for a standard serious civ.
While I don't have any particular concept for her, she definitely seems the type for land units, somewhere the catfish would be weaker. (Having her be intended mostly as a counter to the Catfish but still usable on her own would be ideal.)
I would definitely suggest Meiling herself as a hero unit, with no terrain penalties (to counter all that marsh) and a great general bonus to her fellow warriors. This also has the added benefit of subverting the tired lazy Meiling meme.
. Doesn't help that the only free time I had was last fall, which was used to try out Shogun 2 mods.
