Whenever Nintendo releases a new system, consumers expect a Mario game and for good reason. The two have gone hand in hand across multiple platforms, including the Super Nintendo, Nintendo 64 and DS.

The Switch has captivated Nintendo fans across the world. But some of these fans might be too quick to write off the Nintendo 3DS right now.
You're damn right is it still valid! I'm looking forward to their titles coming out this year for it. Not dead yet!
The biggest reason, its still getting unique experiences and exclusives instead of port after port.
3DS is still way better IMO, the software library on Switch isn't even close to that of 3DS yet. Switch is currently just a bunch of last gen and indie ports, with a few heavily downgraded modern games sprinkled in.
Goes in my pocket without getting the screen messed up and has a huge library of games.
I have great games for both my Switch and Vita but on the go I’m just too rough on things.

It’s always hard to watch a beloved series fall on hard times. It’s even harder still when the problems holding it back are glaring and should have been as easy to spot as Godzilla stomping through a nitroglycerin plant. Alas, for one reason or another, crippling problems either manage to go unnoticed or disguise themselves as a game’s main selling point. Most often it’s a new feature that sounds exciting on paper, but winds up a disappointment in practice. Case and point, the slow yet drastic decline of the Paper Mario series.
Sticker star was horrible I hated it but I liked color splash and feel it didn't get the attention it deserved. Color splash and super paper Mario might not be like the old rpg paper Mario's but that doesn't mean they can't be fun, you just have to have an open mind
I love the paper Mario series they are not anywhere near bad games sticker star was awesome. Just because you don’t Level up like a traditional rpg doesnt mean the game sucked. get over it.
Colour splash was a fantastic entry ... Shame bugger all got to play it, one of the last great on WiiU

With plummeting sales and a fanbase becoming more dissatisfied, is it time for Paper Mario -- a once lauded RPG spin-off -- to be put to bed?
Well the last Paper Mario game has no chance of selling pass 1 million like the rest of the series has, so you could say it's dying. This wouldn't be the case if Nintendo would just listen to the fans and try giving them a sequel that built off of the original and TTYD mechanics
Until they go back to the good version of paper mario, it's already dead to me.
Did you not watch/read about GDC?
