As a Sony fanboy, this is just... why are people excited about the prospect of using a games as service style subscription model in order to play games they have probably already purchased 3 times?
Sometimes us gamers are pathetically easy to manipulate.
Hooray for Nintendo's fat wallet!
I guess it would be like if Sony brought out a new handheld and said "OK for 20 bucks per year we will give you access to all of the old classic games from PS1 and PS2". I'd be pretty keen on that.
As it stands I currently have no way of playing old NES and SNES games without hunting down the old consoles or going in for one of these "classic mini" consoles.
Even if I just wanted a quick shot of Ninja Gaiden, Donkey Kong or Double Dragon for the hell of it, I can't because I don't have access.
So I've got this portable device sitting here and they are saying "listen for 20 bucks a year we will give you access to F-Zero, Super Metroid, Mario World etc anywhere, any time". Sounds pretty decent to me.
You might as well be asking "why are people excited about a thing that doesn't excite me". I dunno, they just are.
Sometimes us gamers REALLY like to overthink things.
1 - I can afford 20 bucks a year, no problem (actually I just got 12 months free on Mario Maker 2 so I am good up to mid September 2020).
2 - I have a fondness for SNES and NES games from my childhood. Even if it's just a 10 minute burst I find them enjoyable.
3 - I do not have a SNES or NES handy nor could I be bothered to go looking for one plus games etc.
4 - I do have a device that is specifically made for gaming and I can play it on my TV at home or handheld wherever.
I don't see how that's being manipulated?
I am getting something that I want at a price I can very easily afford.
What's not to be excited about?
As I said, I think you are overthinking it.
