Digital games and physical games are the same price on the Nintendo Switch. They were the same on the Wii U, the Wii as well. Nintendo never stopped selling physical games. It’s the same on PlayStation as well with the same price. At least it was on my Ps4. The larger piece of plastic didn’t cost more in the 90s compared to the smaller piece of plastic in 2023. The manual/handbook also didn’t cost anything noteworthy to produce back then. I really don’t know where you are pulling these costs from.
