I bet they make more from re-releasing ports of “vault” titles than they would keeping them for sale forever.
I think they would have. those games are all available on the 2nd hand market easily. I don't mind paying for remasters of games I already own for older hardware, anyway, because remasters are not a big expense for me and by buying remasters I send my vote that I want remasters.
I mean, it's Nintendo's IP. they can do what they want. I think the way they do things is very short-sighted, though.
I don't need it to be perfect.
I think a new port requiring a new purchase seems fair, and there's a target market in that one for those who missed those prior generation of games, or who want it on the switch hardware.
Believe me; movie studios and game companies have re-releases down to a science. Disney (arguably) perfected it first with their "Disney Vault" scheme. It increases the value to buyers when it's available for sale; and it also helps the company if there is little new content to offer for the year.
I'm surprised so few people put together that Super Mario 3D All-Stars is actually Nintendo perfectly following the Disney Vault script.
