>>54625967As long/short as they need to be, 10 minutes max (This is how long it takes for the Switch to hit sleep mode, since people won't be touching their controller during a cutscene, Fire Emblem engage has shit that will literally go one for 10+ minutes IIRC and it was a major critique from certain people)
That said it is always best have a skip options for replays or if the game fucking crashes so you don't need to watch and wait out a long ass unskippable thing again for no fault of your own. And you know not Penalize you for it using said skip, Looking at you FFX-2.
Length honestly also doesn't mean shit if the cutscenes are too frequent. several 1-minute cutscenes that happen every few steps is not necessarily better then one 10 minute cutscene you got at a major milestone after a hour or more of pure gameplay just because they are shorter, if anything they can be worse because they keep interrupting gameplay.
And that is not going into what "Cutscenes" are, are attack animations cutscenes?"" Is the Ball Shaking during catch attempts a cutscene? And shit like that that can make it a bit harder to note how short a cutcene should be, especially in JRPGs where some elaborate attack animations can be considered "Cutscenes".
