Literally if you’re playing on the original NES controllers made in a time before Nintendo understood the importance of erganomics. The corners dug into hands and even the buttons wore at fingers and I say that as someone who has naturally thick callouses.

Iirc, they didn’t even have the satisfying button press mechanism most buttons have these days where the button resistance drops as you pass the threshold of a “press”. And many games involved mashing or holding buttons. Like it was painful to watch my daughter try playing SMB and not just hold the B button to constantly run.

They were iconic but I prefer to see them than use them.
