Just Dance is pricier because it's a late port. Come on now, you know it.
And Puyo Puyo justify his price with some goodies included in the box.
Rime is also a late port, so it should be pricier? Yeah, that argument doesn't seem very logical. And the retail version of Puyo Puyo Tetris doesn't come with any goodies (the keychain isn't worth 10 USD anyway) in Europe, nor does the digital version. Yet both are 10 EUR more expensive than the PS4 version.
Puyo Puyo has Digital parity with the other versions (at least in the US). The physical is more but most of us are fine with that.
Just Dance 2017 Gold Edition (Includes Just Dance Unlimited subscription) - PS4 $59.99
is comparable to:
Just Dance 2017 Switch (Includes Just Dance Unlimited subscription) Switch $59.99
The only other console World of Goo is on is the Wii and I think it was 15 or 20 dollars. I totally expect it to be that price or lower. It is an established fact that PC games will quickly sell for less than consoles and I do not think anyone is arguing that the price needs to stay consistent for the entire life of a product. World of Goo on PC/Mac launched at $20.
But I could be missing something. I'm not claiming to be an expert.
Puyo Puyo Tetris digitally is 39.99 EUR on Switch in Europe and 29.99 EUR on PS4.
Just Dance 2017 on Switch is 59.99 EUR, on Wii U 49.99 EUR.
World of Goo is 3.99 EUR on Android and 15 EUR on Wii, on PC it's 10 EUR right now. Will it be 3.99 EUR on Switch? Highly doubtful.
Different prices on different platforms do happen. Rime isn't an isolated incidence, and it's not even the only example on Switch.
