Character interaction tends to be the main character with the NPCs in their quest. So there is decent interaction there, just not as much between the playable characters. There is more interaction with playable characters than OT1, thanks to paired stories and the end game, but the game is still mostly structured around each character doing their quests separately.

I think Trails games really shine in their character interaction. I enjoy that, though I still liked OT2 for being its own thing.
