I mean personally I wouldn't want to game like that on my phone, as it will almost certainly kill the battery and I need my phone for.... well phone things.
But I don't really see why it being $60 is at all weird. It's a $60 AAA game everywhere else too. Same game as it is there.
Edit: and it also unlocks the game on m1 or newer iPads and macOS devices... really not seeing why this is so egregious. It's $60 on steam too
