It did seem like the next emphasis would be placed on Dreams or sleeping somehow. I dunno, after the memory erase thing in Cross, and the added Dream Devourer in CT, it wouldn't be outside the realm of possibility for a plot. Like TAKING a "Break" from time and/or space.
I'd like to see a Chrono type game where time has stopped and it turns out you've left your mind and entered someone else's, maybe through one of a series of porals casually and conveniently located in the End of Rhyme. And maybe each portal goes to someone else's mind. And in the end you've been amnesiac Magus all along. I dunno.
Like a multiverse sequel to Being John Malkovich.
But in a way that sounds appealing. If anybody wants to steal this idea and make a game out of it (Square Enix, I know you're reading this) feel free. I will buy it back from you, in mass distribution form.
