I used to play on my uncle's NES at my grandparent's house and Famicom at my neighbor's house, because my parent's wouldn't let me own games. They probably called my parents and said, "Your kid is a super weird huge nerd and won't go outside."

It wasn't until I got a job and bought a GameGear at 7 that I began this stride down the path of awesomeness.

1987: NES for christmas with mario 1 and subscription to nintendo power that came with the first issue.
1993: SNES for christmas
1997: N64 for christmas
1998: bought PS1 after realizing i was missing out
2000: bought dreamcast, soon after bought saturn and genesis to make up for what i missed
2002: PS2
2003: GC
2006: wii
2008: PS3

i still have all of them.

Despite my gamer pic and username i actually started out as a sega gamer and only when the dreamcast died did my preference move over to nintendo (mainly because of zelda) although i do also love the playstatIon and xbox brands as well. My first  4 console's were all sega, my first was master system (1988) followed by Megadrive (1990), mega cd (1994) and Sega saturn  (1996). Here's all the home consoles i have ever owned.

GEN3: MS

GEN4: MD, MCD

GEN5: SS, N64

GEN6: DC, PS2, GC, XB

GEN7: WII, XB360, PS3

GEN8: WIIU so far

Thanks for these replies, you are all beautiful people.

Thank you, but it was still nice.

In 1982-1984, I played a lot of arcade games, my cousin's 2600, and our Radio Shack TRS-80. The TRS-80 was a monochrome computer and most of its games were direct knockoffs of popular arcade games like Pac-Man, Galaga, Space Invaders, or Scramble. The first video game I can remember playing was Donkey Kong.

1984-86 we had a TI-99/4A computer. It had unique games like Tombstone City, arcade knockoffs like Car Wars (Dodge 'Em), Munch-Man, and TI Invaders (you guess what games these were aping).

1986, my mother got an Atari 130XE. Best gaming machine of the 1980s other than the NES. I had hundreds of games for it that my uncle acquired from me through "warez" organizations, LOL. Among other things, it had the best home version of Donkey Kong ever made (far better than the half-assed NES version) as well as some RPGs.

1987, my best friend got a NES with Mario, Zelda, and Metroid. I was hooked on Zelda for months and also played Zelda II when he got that. But I never had my own NES.

1989, I got the first console of my own, a launch Game Boy, for Christmas. Loved that thing. Came with Tetris and Super Mario Land.

1991, got a PC. Horrible sound and its action games were nowhere as good as console or arcade games, but I loved games like SimCity and PC-Hack (precursor to Nethack). Also into Ultima. In the arcades I played Konami's licensed beat-em-ups and the first edition of Street Fighter II.

1994: SNES bundle with Zelda for Christmas, also got Mortal Kombat II, Zombies Ate My Neighbors, and Battle Clash for my birthday. A year later, I got Donkey Kong Country, Final Fantasy III (VI) and Super Metroid. Still have the SNES and its games.

1996. Nintendo 64 with Super Mario 64 for Christmas. Was playing Virtua Fighter 2 in the arcades.

1998: The PlayStation, the first console I ever bought for my own, with Final Fantasy VII. Loved all the RPGs and still have most of them. Got Ocarina of Time on N64 and a Game Boy Color for Christmas.

2001: PS2 with GT3. Got Final Fantasy X the day after Christmas, Virtua Fighter 4 shortly thereafter. Bought a lot of games for it, too. Also got a Game Boy Advance.

2003, birthday: Gamecube with BloodRayne, Skies of Arcadia, and Zelda: Wind Waker.

2005: DS on my birthday.

2007: Wii and Xbox 360. Loved the Wii and enjoyed the 360 until it crapped out from the E74 error. It died right after the one-year warranty was up but before Microsoft started covering E74 under its three-year warranty for the RROD. I bought a used 360 rather than pay Microsoft to repair it, but after that, I was kind of done with the Xbox line.

2008: PSP

2009: PS3. Got it for Valkyria Chronicles, along with a lot of other games.

2013: Wii U, 3DS and PS4.

2014: PS Vita TV.

I'm a little fuzzy on some of these dates (indicated by asterisks), but this is my best guess. I've never sold any of my systems...my setup just kept expanding and eventually split into 2 rooms.

1983: played my first video game on my cousin's Atari 2600
1986: my family got the Atari 5200, the first game console in my house that I knew about. Turns out my parents had a Coleco Telstar Colormatic packed away in a closet and never mentioned it until after we got the 5200.
1987: Got the VCS Cartridge Adapter* for the 5200 to play 2600 games
1992: Got the NES. This was a life changing event.
1993: Got the Game Boy
1994: Got the SNES
1996: Got the N64
1997: Got the Virtual Boy
1998: Got the Sega Saturn
1999: Got the PlayStation
2001: Got the GameCube, Game Boy Advance, and Dreamcast
2002: Got the Sega Genesis and PS2*
2003: Got the Sega Master System* and Xbox*
2005: Got the Intellivision* and Commodore 64* (no longer works)

2011: Got the PSP
2012: Got the 3DS XL and Sega Game Gear*
2014: Got the Wii U and PC Engine w/ CD-ROM2

There's not enough ones like you left. 

Another old school king. Holy shit.

We also had a Pong machine from the 1970s. It was a knockoff machine. It belonged to my older sister.
