That's an interesting view.
Personally, I think both games will be good, but one will win in sales. That will be Crystal Bearers because: a) it's Crystal Chronicles game that doesn't dick around with the single player focus and b) it's Final Fantasy.
Aside from the Japan only Silent Hill GBA game, Silent Hill hasn't been on alot of Nintendo consoles. I found it was slipping in popularity after the fourth game (the third on the PS2).
