Select was a weird button on the NES controller. Like, toggling between menu items? Can’t we just use the D-Pad for that? But it seems like more games than I remember used Select, according to RacketBoy
There’s even games on the list I played the hell out of (Captain Skyhawk, A Boy and His Blog, Metroid) that I don’t remember actively using Select for anything. It became automatic, and then faded from memory as a useful button in my gaming youth.
The best items on the list are the games where Select pauses, because Start is being used to select a menu item, weapon, etc. Not even the developers knew how to use Select consistently!
