The ending, final boss, etc. [Obviously spoilers]

[Alphasoldier]

So what you're saying is that Naija and Li got a son and that that son had alot of godlike powers which he used to create a city in the sky, because he was able to because he is half human?
I think that's a bit too farfetched.
I think the humans just rebuild the city.
Further I'd have no clue what the son would want or do there.

a. The Sunken City IS the city you see in the intro. Either that or a recreated copy (in the eyes of the little boy longing for his home). Not to mention that in the ending of the game, he speaks about it IN PAST TENSE. So yeah, there won't be any flying city in the sequel

I can definitely agree with you there - I don't know why anyone would thing anything else. Though just because one flying city crashed into the waves doesn't mean there can't be a different one in a sequel...
The other stuff, not so sure, they seem to be fairly large leaps to make from what we've seen, certainly too much for me to be 'close to %100 sure' of their truth.

There is only one thing you all forgot. The door... If the creator recreated the city, why he put this massive gate at the only entrance? And why only Li had the key/used to know how to open them? It's rather funny to think the only purpose of the door was to stop Naija or Mia from entering the city. And the details familiar from those from the city in the intro - isn't it obvious that just Alec and Derek used the same tiles? If the people had the same tech tree, all the cities can look quite similiar, but the sunken one even doesn't look similiar at some points to the one from intro at all.

I can still hold to the creative version of the city or still believe it just crashed into the waters, but then it would be just too complicated. Maybe there's also a story before everything started... Imo, this city has a symbolic sense. It uses to show the weakness and vanity of the human kind. Everything we create, no matter how huge it would become, won't stand the test of time and will finally turn into dust an rubble. I know Derek has a way to come into the details, so when you look at sunken city, you see it's attached to the ground (all those walls in the background, all those pipes 'n stuff). If it would fall through the waters we would propably see a pile of rocks, rubble and twisted steel. This of course doesn't mean the city couldn't be recreated by the Creator, but... If he had so trumendeous powers, why the city looks like a giant, underwater ruin? In that case there are only two answers: He didn't/couldn't succedded as with the rest of his creations (flawless things), or he just wanted it to look like this.

Anyways, at that time topic tells very much 

[KingAl]

Hmmm? I'm arguing for it being the real deal, not recreated. That Li can open the door suggests that it's a door from Li's civilisation, and it seems likely that Li was there to research the crash of the city itself - I didn't 'forget' the door, it's a key part of my understanding. I think it's silly to argue that it's just that the same tiles were used, as new ones could easily have been created, unless overlap between the two is intentional.  I believe the inclusion of the exact same fountain - which is included very clearly in an otherwise sparse screen of the city in the opening animation - is a very deliberate attempt to make you connect the two. It isn't just a generic design either - a dude with a bird on his arm held up by fish is not the sort of thing you'd expect to be popping up everywhere  There is a thing called 'suspension of disbelief', you'd do well to look it up Suffice to say, in the world of Aquaria, it's entirely possible that a city which crashed on the water wasn't entirely obliterated - keep in mind the city was sitting on top of a huge rock base - particularly when the creators make a point of showing it to you.

[Alec]

I'm kinda worried about posting here, (I don't want to ruin too much about the sequel, and its interesting to hear all the different interpretations) but I want to clear up a couple of things.

The world of Aquaria is 3D, (i.e. if it was a real place you could visit, it would have a Z axis) but it is presented in the game as 2D. I think this is leading to some of the confusion.




A couple quotes of interest:

"Li was particularly excited by these ruins...
...it was if he recognized them.
They did not look like the work of Aquarians.
I suspected that they were from beyond the Veil.
Perhaps Li's world was destroyed as well..."

"Perhaps". This is only Naija's assumption, its not explained in the game where Li is actually from. (although we can guess it was either the city seen at the beginning, or a similar one; since there don't seem to be any other living humans in the waters) The only human Naija knows at this point is Li, but she also has no knowledge of anything that exists outside of the waters. Naija picks up that Li is lonely and searching for something, but she doesn't know why. Derek and I do, but I don't think we'll get into that until the sequel.

"There are much greater worlds above ripe for the taking." - Mia

[Alphasoldier]

Okay, even though this explains some, it also doesn't, it's not answer to if Creator made it or if the city crashed. Yes, I already knew Aquaria is a bit 3d, multiple layered, seeing you have open waters and caves,  which reminds me a bit of Metroid again, but I just think of Metroid too much.
And about the door. It still opens. I mean, what door still opens after crashing hard? And IceD like you said: "Everything we create, no matter how huge it would become, won't stand the test of time and will finally turn into dust an rubble.", so did the ruins from the city. At the beginning he wanted to recreate everything, but after long times he saw that everything slowly became corrupted and stuff, well, so did the city.
I still hard believe that the creator recreated the city, just because of the reason that it is almost impossible that it's very deep in the ocean, even under the most things.
And well, earthquakes exist, but that would make the ruined city even more rubbled.
And about the door, he just wanted Li with you to annihilate him, right?

[Xiagan]

I think it was plain as hell before but now, with Alecs explanations, it is überclear that this "sunken" (= at some point it was above the water) city is the one that crashed into the sea. There are even ghosts of the people that lived with Eric in the flying city!

[Cruxx]

 I dont think its called "sunken" city for nothing. if the creator merely re created it, it would be called something else, combined with the fact that the big gateway still exists, i think it is the one which crashed into the sea..

[IceD]

Yeah, I can finally agree with this. Lets be honest - sunken was the flying city. It was a big piece of rocks and ground so when it has fallen, it propably laid down onto the bottom of the sea, merging with some of it's underwater ground. So the door could be also an entrance gate to the city  . Li propably knew this, if he only came from similiar town like this one  And he was propably searching for this lost city (adventurer & scientist in one, just like Indiana Jones ). The rest of reasons are more or less unknown.

Lets stop spoiling and predicting stuff. It will be better to wait for the sequel, then we will see and our curiosity will be fulfilled 

[Alphasoldier]

Man, you talk like every thing you thought of is right, you peopel didn't even think HOW those rock would perfectly stay above the city and there are no rocks even on the floor, the door still works, but Naija doesn't even know HOW to use a door, seeing the first one she had she SUNG it open. So she needed Li for that. The "sunken" city has aged and it's called a sunken city as it's underwater.
I just see almost no chance that the city would be so intact if something would be collapsed ontop of it and that the door still works, it all just doesn't make sense if the city actually FELL into the water.
And so far I can read, Alec said nothing about this being the actual sunken city. Just being a city underwater and being samiliar to the flying one.

[Alec]

It makes sense to me that it fell, for reasons described above.

I think if anything its a visual thing that you're confused about. The city really isn't intact.

[Alphasoldier]

Well, ok, but alot of buildings are too intact, no half buildings and stuff, but I guess that's searching it too far. Though this does mean you just confirmed that this was the flying city.

[Alec]

The presence of the Creator/Eric's spirit helps explain why things are arranged nicer than they would be under normal conditions. Presumably he tried to fix things up as well as he could. If you think about it, that area is largely a projection of what's in his mind. The insects are tied to faceless children teasing him, the girl that he cared about is there in as a spirit, presumably called there by his power. The mother and father boss are his interpretation of his mother and father. (this is hinted at when they turn back into spirits)

The presence of a human door is symbolic to how the Creator feels about his human component. (its locked away in the dark, while he tries to forget it and pursue other things)

The sequence where the Creator kidnaps Li points out that the Creator and Eric's spirit are two separate entities, but they are connected. The ending goes a bit further into that.

I think the identity of sunken city being the flying city in the beginning is explained pretty clearly in the game when you talk to the ghost kid at the end where he shows you the flying city from the intro while talking about "on that day everything changed".

[Alphasoldier]

Well, seeing it's not exactly stated in the game, anything would've been possible, but now that you've stated it... Thanks.

[Cruxx]

 Well there you go alphasoldier, you were looking into it way to deeply, honestly, if the city fell, it would have been shattered. Thats just going uuber deep.!
