If you're including PCs, then I got one of those when I was 8, back in 1988. It was awesome. Somewhat technically inferior by today's standards (512KB of RAM, no video card obviously, no hard drive, 16 colour display or four colour if you ran it at a resolution high enough for anything to actually look like something). But man I had fun. Hero's Quest, Space Quest, King's Quest, Zak McKracken, weird budget games that were terrible but made me so happy. Prince of Persia! Brilliant.
