I owned to guide (brady) yet didn't feel the need to look through it, and the game was fabulous, i went back to beat it in multiple ways. (as you can tell, I really liked sephiroth) However i did look through the chrono cross guide and they did a good job not informing you *SPOILER* of when you switched bodies with linx, they mearly said something along the lines of "you're now playing as a new character" and that was all , I think they learned over time.
