Very simple poll. Yes / No / Undecided.
And if possible post your reasoning.
As for myself:
I won't buy it because I see no reason to.
I have almost exclusively singleplayer games on my Switch, don't care about cloud saves and some NES games.
So far the service does not offer anything of interest for me. Even for $20 per year it's not worth it for me currently. Maybe if the libary of oldschool games gets bigger and adds some more interesting games.
