The membership offers acces to a library of N64 and Sega Genesis games + free access to the Animal Crossing DLC.
It will cost $49,99 a year, $79,99 for a family pack.
This seems too expensive in my opinion as it more than doubles what you have to pay otherwise, Playstation and Xbox online are still $10 more but offer much more in return. Also, the Animal Crossing DLC is only freely available as long as you have the subscription. This makes it cheaper to just buy the DLC for $25 than renewing that expensive subscription each year.
As much as i want to play Banjo or Star Fox 64, i think i'm sticking with the old subscription.
bonus: you can buy a collection of Mega Drive and Genesis games on Steam for $30 which is also cheaper in my opinion.
