3ds- I've owned a total of four over its life time. I think I have nearly twenty games for it.

Wii U- owned a total of two black consoles because my original launch day console broke a month after. I'll probably end up keeping it but its only gonna come out of its box for special occasions.

Switch- Bought it day one and really looking forward for the next few years of Ninty games coming to it.

3ds: i have 3, one 3ds from japan, one 3ds from portugal and one 3ds xl from US ( i had a comum 3ds from USA but my sister broken playing cooking mama long time ago ).

wii u: i have one from USA ( zelda wind waker edition )

Switch: i plan to buy in july ( I'm going to travel to New York and I'm going to buy the switch there )

Got a 3DS and a Wii U.

I'm in possession of a N3DS XL, WiiU and Switch. Basically a newborn Nintendo fan in my older days :).

3DS:
Do you own it, and how many? Planning on getting one? Do you still play it?

Yes - 2 - NA - rarely

Wii U:
Do you own it, had owned one and sold it off, or planning to get one? Which version? Do you still use it and for which games?

Own/keep - Deluxe - rarely (kids play random and VC myself)

Switch:
Do you own one? Or want to get one but can't because of stock? More importantly, what games do you currently own and which ones are you for sure planning to get?

Yes - Own 2 - Zelda/Bomberman (see sig link for all games)

3DS: Yes, 1
Wii U: Yes, no longer play. If did would probably pop in TP or XCX
Switch: Yes, Zelda. Not gonna bother listing planning on games.

1. Only ever owned the blue launch 3DS. Still occasionally play games on it.
2. Launch Deluxe Wii U. Rarely play games on it.
3. Have the one with black Joy-Cons. Only have/playing Zelda. Currently, only other game I'm 100% getting is Mario Odyssey.

3DS: Nope, I skipped it.

WiiU: Deluxe model, only bought Starfox Zero and ACIV retail last year, plus a bunch of eShop sales. Giving it to my sister sometime in the future.

Switch: Neon, BotW and Snipperclips, Puyopuyo Tetris next.

Haha, yea, I'll probably play it till they stop supporting it

3DS: red 3DS XL. Still play it occasionally (but I prefer my Vitas)... still have to finish Majora's Mask and Bravely Default. Will keep it for my DS and 3DS games.

Wii U: black Deluxe model. Will keep it for my Wii and Wii U games... still have to finish Skyward Sword, Windwaker HD, Twilight Princess HD and a few non-Zelda games

Switch: will buy it when Super Mario Odyssey releases or when the first Switch revision launches in 2018... Breath of the Wild can wait until I finished the other Zeldas above
