In 2008/2009 when I first bought a big LCD TV & consoles and set up 5.1 sound I really felt in love to console gaming. So PC also connected to a TV as a second screen. Love to play gamepad-based games on TV OLED screen lying on sofa rather than sitting near IPS monitor.

Younger Brother got a DS Lite that I occasionally used in 2007, Brothers got an Xbox 360 Elite in 2009, Older Brother got a PS3 Slim in 2011 (used them both a little bit, but the PS3 very rarely and the 360 a little).
None of my computers have been gaming PCs but...
2015: Opened up my Steam account and did some gaming on a laptop
2017: New laptop but not a lot of gaming
2021: New Rig with an SSD and more RAM but very little gaming (hoping to do more on Steam and with Xbox).
Future platforms I'd like to get.
1. Xbox One: Probably the S, because the X is expensive, and the "VCR" has a worse processor and is bulky.
2. PS2: Probably the Slim. I've played a bit on a PS2 that my grandparents got in 2003_
3. SNES

I've been playing video games as long as I can remember. My first console was the Mattel Intellivision, which I received as a hand-me-down from my father some time in the mid 80s. There was also whatever arcade games that caught my interest as a kid. Subsequent consoles gifted to me or that I bought were:

NES (Christmas gift in 1988)
Genesis (Christmas gift in 1991)
Game Boy (can't remember exactly when I got it; definitely in the very early 90s)
SNES (Christmas gift in 1994; last system received as a gift from family)
PS1 (first system bought with my own money; purchased in summer or fall of 1998)
N64 (purchased some time later in 1998 or early 1999)
Dreamcast (purchased on the 9/9/99 release date)
GameCube (purchased with tax refund in 2002)
PS2 (can't remember exactly when I bought it; some time in the 2001-03 time frame)
Xbox (roommate let me keep his second Xbox for playing LANs back in like 2004; later gifted to another friend after I bought a 360)
Xbox 360 (purchased with tax return money in 2007)
Wii (purchased with stimulus check money in either 2008 or 2009)
Wii U (purchased August 2013)
PS4 (pre-ordered and picked up on launch day in 2013)
3DS (purchased in March 2014)
XBO (purchased in November 2014; traded in for One X in Nov. 2017)
Switch (pre-ordered and picked up on launch day in 2017)
PS5 (pre-ordered and picked up on launch day in 2020)
Series X (purchased in June 2021 when GameStop had a rare in-store restock)

I will probably buy a Switch 2 as early as possible and upgrade to a PS5 Pro, money allowing.

Idk the exact year's I got them so I'll just put the systems more in release order. My earliest gaming memories are playing Super Mario Land 2 on a yellow Gameboy and getting a ps1.

Gameboy, PS1, GBC, PS2, GBA, GameCube, Xbox, DS, PSP, Xbox 360, PS3, Wii, 3DS, Vita, WiiU, PS4, Xbox One, Switch, Xbox Series S+X, PS5.

Basically I've owned every current PlayStation, Nintendo and Xbox console except the N64 while I was alive.

I bought an n64 later at some point and I've also gamed on PC's since I was a kid too.
