Mine, Faces of Mu, was born from the SNES games Illusion of Time and Terranigma, and a bad memory. In IoT there was a sunken place called Mu that I think stuck in my mind because it had eerie music. It also made me think of the myth of Atlantis, but I don't know if that's really what Mu was about. Terranigma also had a similar place, and I think it had some imagry of the large Moai heads seen on Easter Island. So, to instill some mystery and perhaps be a little creepy, I chose Faces (Moai heads) of Mu. If anyone remembers either of these games and cares to enlighten me about how these images might interact, I'd appreciate it!
I'm curious where you played IoT, as it was called Illusion of Gaia here in the States when I played it as a wee child, and AFAIK Terranigma was never released here (but thanks to the magic of emulators, I've been able to try that one too; didn't get far in it though). But yeah, Mu and the underwater palace are definitely amongst my favorite areas in the game.
I'm not overly familiar with Mu, only that it was allegedly another "lost continent" like Atlantis. I think I had heard about it from some show that was "investigating" the latter (yeah, I was big into that kind of stuff as a kid; still am, in a "people thing up the weirdest things" kind of way).
Wikipedia helps with the connection to the stone heads from Easter Island:
In his attempt to create a vivid description of an ancient yet lost civilization capable of explaining the greatness of the “white” race, Churchward connects several civilizations. He includes Egypt, Greece, Central America, India, Burma and others, as well as Easter Island. These are all cultures that are known for their megalithic art and architecture and have been a topic of interest for scholars for centuries.
I can't really say anything about any connection that Terranigma might have with any of this, as I didn't play much of it and am not familiar with all the locations.
Now, that fun sidetrack out of the way, my name:
Back when I played MMORPGs, I almost always used the random name generator. One of the names I got for a character was Oosen; you can probably guess how I got Nesoo (for another character) out of that. I've used Nesoo, or its shorter form, Nes, pretty much ever since (though you have to be careful; I only use "Nes" in a handful of places, and there's a lot of "imitators" out there... I'm sure the fact that it happens to be an acronym for an old video game system doesn't help...).
