This is a strange topic for the older gamer as (and I'm sure Socratic had the same memories looking at his account) my first gaming experiences can't be divided into the clear PC v Consoles split that exists today.
I started with Game & Watch, TomyTronic 3D & Puck-man. Sided with the Commodore 64 rather than the Sinclair ZX Spectrum & was introduced to Lemmings via the Acorn Archimedes.
Finally got into consoles via the Sega Master System, then Game Boy, SNES & N64. Had to buy a PC for non-gaming purposes, which snuck PC gaming into my life. However most of my peers were still consolers so I tried PS2 & XBOX 360, but after PC gaming it just didn't appeal any more. So I'm onto my fourth PC and don't imagine ever abandoning PC gaming again. But I still have a soft spot for Nintendo. Where as Sony & Microsoft's offerings seem like underpowered PCs, Nintendo has always seemed to push the envelope. I bought and enjoyed the social aspect of the Wii & intend to get a Wii U in the near future.
