Well?

Nope. I will not touch it to be honest

I will eventually

Once I get the game I will=p
Waiting for both Splatoon and my copy of Kirby: Ranbow Paintbrush to arrive :p

Yep.

I beat every level, and grabbed every scroll.

I absolutely loved the soundtrack of single player, and all the bosses were pretty fun as well, especially the final boss.

Played through the whole thing and while there were some really boring and tedious parts, I really enjoyed it, especially that final boss. I'm probably gonna go back to try and get all the sunken scrolls soon as well.

Haven't beaten yet, on 4th zone/section/world/whatever. Definitely fun n enjoyable and much different from online play. Will probably find myself wishing it was longer once I beat it.

Wynaut!?

... I had to really, needed to finish it to unlock the weapon I want.
Final boss made all the other boring missions worth it.
If they make a Splatoon 2 (and we all know they damn well should) they really need to work on the campaign.

I have not and won't.

I answered yes, but not finished as all of my children are playing the solo campaign.

I will only play the online or local battle modes.

I'm going back and forth between the campaign and online, and I have to say I'm really enjoying it. It really feels like a new age 3D platformer. It even has a hub world. *cries*
