The only Sony amiibo I would ever care for is for one of Crash Bandicoot. (and Cloud Strife, but he's already getting his own Smash amiibo anyways. )
Other than that, IDGAF.
"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."
