I've owned every Nintendo console and handheld (besides the GBA) from the Gamecube onward.
I don't own a Gamecube anymore, sadly. One of my favorite consoles.
I currently still have my GameCube, 3DS, and a Switch Lite. I used to have an N64, SNES, DS Lite, Wii, and Gameboy Color but they've all been sold, stolen, or discarded.
NES phat, SNES, N64, Gamecube, Wii, Game boy color, gba, gba sp, DS Phat. I had a switch but gave it to my nephew. For sure I have my gamecube and wii near by in a drawer. My NES and SNES are probably in the garage or in the closet in my parents house. I hope they still work.
For home consoles, I own a Switch, Wii, Wii U, SNES Classic, Super Famicom, and a Nintendo 64. I’ve considered saving up for a GameCube, but my Wii plays them fine.
As for handhelds, I have a DSi, 3DS XL, 2DS, New 3DS XL and a Game Boy Advanced SP.
I usurped my brother’s N64 and GameCube, and I have the Wii, Wii U, and Switch as well. My family owned an NES and SNES in the past but I’m not sure where they are and have never actually played them, so I didn’t count those.
Also a bunch of the Gameboys (color, advance, advance sp, micro...) and the DS, DS Lite, DSi and 3DS
Dunno why I have dupes tbh but hey what can a guy do.
Just the Switch from the poll but I do have a Gameboy Advance SP, 2 DS Lites, an OG 3DS, and a 3DS XL. Reasons I have multiple DS is my clusin gave me his since he wasn’t using it. As for the 3DS, I mainly use the XL but the OG one is the Japanese version which we got due to the region locking back in the day.
I've been fortunate enough to own all except the N64. I've since sold them all except for the Switch. Around the time where a new platform is released, I bundle my consoles with all its games/accessories and sell it. This helps pay for the next console. Time is limited anyways and I don't have the time to play all of them.
Had the NES and SNES when younger (yes, old enough to remember those days -- 1988 to 1996 for me!). I bought another NES in the early 2010s and relived my childhood for awhile. Didn't have the N64 through Wii as I wasn't gaming much when those consoles were current. I did PC gaming sporadically from 1996-2006 and didn't get into console gaming again until the PS2 in 2008. I then got a PS3 before returning to Nintendo with the Wii U in 2016. Upgraded to the Switch last year.
I've owned all of those at some point or another, but I currently own a Wii (Japanese), Wii U (Japanese), Switch (US), the NES Classic (US), and SNES Classic (US).
I've also owned all of the Nintendo portables at some point or another except the Virtual Boy (ugh that headache inducing thing!). I currently just own 2 DS Lites, an original 3DS, a 2DS, and a New 3DS XL. I keep the DS Lites around because I still have some GBA games.
