What are some of the hardest bosses you've ever fought?
Two bosses that stick out for me in particular are Ornstein & Smough from Dark Souls,
and Wily Capsule 7 from Mega Man 7.
"Just for comparison Uncharted 4 was 20x bigger than Splatoon 2. This shows the huge difference between Sony's first-party games and Nintendo's first-party games."
