You may be onto something, BackwardsSubmachine: The memories may not be OUR version of the Player's memories, but the Player previous to ours, or even a culmination of ALL Players previous to our "version" of the Player.
Do you mean why I started this discussion?
I find this thing interesting.
Actually, many years ago, when I first time played FLF, I thought that it is part of main storyline, between Sub4 and Sub5, and Player is main protagonist here, and this speech is said by him, and FLF location is part of Subnet. I called this location "Memories Storage". And Player, who lost his memories in Submachine, retrieves them at the end of this game. It's all coming back to me now...
...and I almost remember my name. I know where I must go now... ...to find the root of all of this If he fails his mission, his mind would be... absorbed by Submachine. Where is located this "Memories Storage"? Inside Submachine, and inside human minds at the same time. They should take their memories back. Or they will die...
That is what I thought long time ago. And I still wonder what SubFLF actually is.
I know you realize it's probably debunked by now (this Theory of yours), but, if indeed SubFLF was even a part of the main storyline, how come we never see anymore to this part of the storyline? We jumped straight into the Root, the Edge, the Core and the Plan, with nothing explaining memories - We're just as lost memory-wise as we have been in Sub1, except we know we were trained to work with Wisdom Gems (which is besides the point), and that there were Players before us.
I mean even I had the "Core Stores the Corpses" Theory, which is obviously Debunked, but I'm starting to believe memories fueling the SubNet (or some form of that Theory/statement) is Debunked.
As my Theory goes, we've only seen Karma and Wisdom (both energies), no "Memory Energy"...as of yet, at least.
And even if Memories aren't an energy (I know you're not proposing it as an energy, this is just my analysis), then what purpose do memories serve in the SubNet? Is the SubNet a hub of human memories, like a sort-of Museum, preserving human culture, as the Core was intended to do? I'd say that's Still Alive/Likely.
