The thing is, if you've been neglecting it for a while, you might be logging into zero Platinum Points, which doesn't really help you pick up 600+-cost rewards. We've shown you a few easy ways to earn points over the past few years, but there's one fairly innocuous mission that a lot of people are probably ignoring right now: the legacy system mission.
While we have no idea when Nintendo will actually realize that this mission exists and turn it off, for now, it's ready to claim every week. All you need to do is log into the Nintendo eShop on a Wii U or 3DS with the same My Nintendo-linked account, and you'll earn 30 Platinum Points per week.
That's literally all you need to do. Just sign in for a few seconds and you can earn 120 easy Platinum Points per month in addition to whatever else you're bringing in. My Wii U is still hooked up and I keep my 3DS fully charged on a dock near my bed (with a docked Vita!): so this is super easy for me to remember.
It's not every day I get to write about the Wii U and the 3DS. If there isn't a reason to, I'll invent one!
