When I was a wee lad(four or five) we had an NES in our house. It was a blast. Legend of Zelda, Super Mario Bros., Duck Hunt, and Castlevania were my favorites, even though I never got past the first level on many of them.
From about seven to ten years of age, we had an Xbox, with a wide variety of games. This era is what got me interested in free-roam RPGs; the first time I played Fable: The Lost Chapters was a very good time.
Then about a year later we got our first Xbox 360. We began with only one game: Viva Piñata. We still have this copy.
Since then my gaming repertoire has grown exponentially: Grand Theft Auto, Elder Scrolls, Fable, LEGO games, and many many more.
