I started a second playthrough. Don't recall how far I got. I'm pretty sure I've recruited Guile (I recruited Pierre the first time). I know I've used every version of Pip because I got to him to a point where the tipping of his nature just required a bit of in-battle prodding. It was annoying trying to get him to change during the battle (by this time, I was fighting Time Devourer at Terra Tower).
