I'm nearing the end of Part 1 on my second playthrough of Three Houses. I went with fem Byleth and the Golden Deer house, and I've noticed some differences so far. The new game+ bonuses make the way easier than it already is, but it's nice being able to recruit characters a lot easier, and have their supports build up faster as well.
Also slowly making my way through Trails in the Sky SC. Just started Chapter 6, and it still feels like there's a lot left. The reunion scene was quite touching. 😢
