I'm about five hours into the game now. I've never played an SMT, Persona or Fire Emblem game before, but I watched the Giant Bomb LP of Persona 4 so I feel like I had a leg up on understanding the Unity stuff. I'm really enjoying it so far; just finished Chapter 1 and I'm in the Intermission now.
Do I need to worry about missing any of these side missions with my team mates? The game seemed to suggest that I should have had Touma at a high enough Stage Rank to play his side mission by now, but I'm nowhere near that and it seems like it's going to take a fair bit of grinding to get there (Touma seems like my worst guy at the moment, and I was looking forward to dumping him for Kiria). Are there going to be Intermissions between every chapter, so I can just do his side mission on the next one?
