Why do we assume that the 7 days Roxas spends in the virtual Twilight Town is real time? It's a computer, right? So, why 7 actual days? And I always assumed that he was in the virtual Twilight Town for longer than the 7 days that we see.
Also, I think the two in the title does signify 2 characters, though I'm not too sure on who those two characters would be. I would love to play as any of the three- Riku, Roxas, and Xion. We don't get to play as females very often in the game, which is why I'm so excited for BbS.
@ Insomniac. I hope it's not exactly like what happened in CoM. Remember, Riku's story only became unlockable after Sora's story finished. If that stands to reason, then Riku's story would only be unlockable after we finish Roxas'- which just won't work.
The story of Riku, Roxas, and Xion are intertwined, obviously from the cutscenes we've seen so far, so it wouldn't work like in CoM, where their stories were seperate, for the most part.
