My fav Mega series is Zero, but MMX holds a special place in my heart due to how all of my cousins would gather together at oldest cousin's house to pass the control around & bash our heads at the challenging bosses and level designs It was also my first memory being like, actually CELEBRATED for an achievement due to blowing through the motorcycle level in one go after watching older cousins fail so often at it that I just learned the level design patterns intuitively lol
