Em... If it's around 20 or 30 bucks a year which they've already stated then the online capabilities is all I need and want to make my purchase.

Offering a service that falls in line with PSN/XBL. Baseline shit.

They'd have to outdo PS+ with games as I haven't played online in a year so games only thing keeping me paying the couple bucks a month.

Have lots and lots and lots and lots of online Multiplayer modes in there games! And it has to be fun! Franchises like:
- Mario Party
- FE Warriors
- Mario
- 8 Player Online Smash

But I would definitely be buying it for Splatoon. Plus the Price looks very nice!

Nothing. As on PC, I won't pay to play online.

A game I really want to play online...

I heard they are giving those who buy it "rentals" of classic games... OK cool. But why not a 15% discount on purchases as well?

User accounts shareable across multiple devices (one active log in at a time would be fine if Nintendo doesn't want a single license being used simultaneously by multiple players on separate devices), cloud storage for game saves, settings, etc. trial access to games, preferably new releases (which would be anything published on the Switch currently) would be a good start.

If Nintendo wants to charge service fees for online access/play, then they need to give their consumers a real service rather than just unlock online play from behind a pay wall.

Fortunately, there are already two well developed services in PSN+ and XBLG for Nintendo to try and match if value is what they want to give their customers.

If it guaranteed a Wii level and beyond VC support.

Splatoon 2.

Nintendo's online is cheap, I don't care that it doesn't have as many features as the competition for this reason. I'm more than willing to pay a couple dollars per month to support their online servers.
