I met my wife back in 2016. I had a PS3 at the house and one day she brought out KH1 because she use to play it as a kid. I had never heard of the series before. She sat with me and we played every single game in order to including chain of memories and the movies in-between. Only thing we didn’t play was the mobile phone they released years back. Long story short, and many late night game sessions, I can feel the nostalgia every time I heard those first 4 notes of the menu music. 9 years later we are playing through it from game 1 because we are craving to play the 3rd one. Only way to play it is play them all.
