As a kid I had a Sega Genesis but wasn't interested in it at all. Got most of my entertainment from novels at the time (Redwall, fuck yeah!).
Then, when I was in fourth grade, a family friend who was an entertainment journalist gave me an advance press copy of Westwood's epic Command and Conquer: Red Alert. At school, we would 'play' Red Alert on large pieces of paper, basically you could do whatever you could draw. Want troops? Draw a barracks, then draw troops. Want a nuke? Draw a silo, but you have to have a Tech Center first. Around the same time, I stayed with a friend who got me into Starcraft. For three or four years after that, I was all about the RTSs.
Then, early on in high school, the event that changed my gaming life forever struck. At the time, I lived in a country where there were no gaming stores (except for copied versions) and at the time there was no Steam. My friends and I would browse Kazaa and eDonkey looking for pirated ripped copies of games to play. We really didn't know better and got a shitload of viruses for our troubles. While my friends were all obsessing over the Myth release of Warcraft 3 or GTA 3, I got carried away with TES3: Morrowind. I played that game for four years all the way up to my high school exams (mostly because I had the same crappy desktop for that entire time). Then, when I graduated from high school, I went out and bought a GOTY version of it, whereupon I learned for the first time that it actually had cutscenes
Ever since then, I've played mostly computer WRPGs. Still can't get to grips with console controllers, I sweat absurdly when I use them and do that frustrated-head-turning thing still.
