I played CoM, Days, and Coded to tide me over but really, it wasn't necessary. As much as I think I would like to play Sleep and Dream, I'm pretty sure I could go without and just skip to III without feeling like I missed a lot. I'm not one of those a-holes who feels completely ripped off when a story hop-skip-jumps an entire segment as long as they get around to explaining what happened in that time.

Point: I do like the idea of B6 in the game... has Frozen been confirmed? I remember hearing something about Tangled.
