Yeah, same. I wonder why that is, maybe the use of instruments? I am not sure.
Yeah, I guess it's like a smaller range of instruments being used is what gives it that vibe for me. It's mostly piano compositions, where PG had so many bizarre and unique synths being used for every hour, it's hard for me to forget each theme, lol.
The first one has the best main theme and best rainy day music. Nothing can touch Population Growing's rainy day theme.
It has such a bizarre and quirky approach to its music that fits the game so well. It's something I feel the series has sort of lost over time. Every entry has great music don't get me wrong, but I feel Population Growing is the most memorable because of its bold and unique sound. New Leaf was also bold in that it went for a more minimalistic approach to arrangements that faded beautifully into the background of your daily activities. It's still great, but, because of that more minimalistic feel, I feel like it didn't find a spot in my memory as well.
Y'know what, this PERFECTLY captures how I feel about the soundtracks.
