Started with Gameboy color and Playstation at 9 or 10, but played the most with PS2

Gameboy Colour and N64 kickstarted gaming for me.

I played on PC before that though.

My fist games were 8-bit Tetris and Golf games on a DOS computer. I think it was called Victor or something.

2nd gen

Magnavox Odyssey 2 or as it was called 'Philips Videopac G7000' over here.
Good times!

4th generation for me, I played the heck out of my Genesis (mainly Sonic games). Didn't actually get my console until the 5th gen had already started, though.

I don't remember for sure which console I played first, either the Master System II (playing Alex Kid) or the NES (with Super Mario Bros 2). Both of them were from 2 different friends.

But my first owned console was a SEGA Mega Drive.

I started with a n64 controller in one hand and a gameboy in the other.

Game Boy and MS DOS. I guess that makes me Gen 4/5.

I started on the Coleco Vision, and my father bought the Expansion Module that allowed us to also play Atari 2600 games on the Coleco system. From that generation, we also played my grandfather's Intellivision at his house.

Started with the NES. Too poor to play video games before that, heck we didn't even own a television until I was 5.

My first gaming experience was the NES, but my first console was the Sega megadrive (genesis in NA)
