Always a PC gamer since mid-80s. I've always needed a PC for work since then, so it never made sense to consider a console—I've worked from home since '90.
My first electronic game early 80s was that 4-in-a-row game. I got a dirt cheap Spectravideo to play around with this new programming thing, and of course what better program to play around with than a game? The machine was like a fat keyboard, plugged into the TV for output and input came from tapes in a cassette player.
Only source of software I knew of was programs printed in magazines. Imagine the joy of typing them into the machine. Imagine checking line by lie when the danged thing refused to run. Imagine then waiting a month for the errata in the next edition!
That lit enough of a fire to make me switch jobs to a hardware—and some software—manufacturer, where I learned a lot about the whole computer industry. The original Prince of Persia opened my eyes to the possibilities for gaming, and I was cemented into the PC world by Wolfenstein 3D and the great RTS franchises of the later 90s.
My main genres are strategy & open-world shooters, so again a console would make no sense. I also dabble in little indie games and also enjoy a good few casual games, neither of which would be available on console.
Got into a modding community
I suppose the biggest reason to play PC for me is the mods. Those guys do some incredible work, and for me have extended the playability of favorites, plus made at least one big fav playable at all. Thank you DP and all your colleagues!
