I am 30, and have played 'almost' every system that was released in the US, as well as a few that never did.
Early childhood memories recall an early frog bog game on an activision.
Had other games for it, but remember that stupid one the most.
Around 6, I had my first NES, and played all the greatest hits. Mario, Zelda, Metroid, Mega Man, Duck Hunt, and many more.
Moved up to SNES at 9 I think, and played Sega at friends houses.
Moved up to Sega Saturn, then PlayStation/PS2, then backtracked to some older systems, N64, so on.
Got Dreamcast for Phantasy Star Online and was convinced the future was online multiplayer.
OG Xbox comes out, and I am too busy playing all the PS2 games. Later pick one up and hack the fuck out of it.
Get a GameCube, love Metroid Prime.
PS3, then Wii. Return Wii after days because I was so disappointed in the Metroid game.
Stay with PS3 for most of its life, then buy a 360 when I felt the failure rate was no longer an issue.
Got a PS4. Here we are.
