First finished on Wii, later began achievement-hunting on Switch via Mega Man Legacy Collection 2. I still have yet to beat the game 30 times, clear it without taking damage, and defeat every boss with 1 pixel of health left, but once I do, I will have officially mastered the Challenges page and earned 100% completion. Mega Man 9 is my favorite game in the franchise, so I believe it deserves nothing less.
