I consider myself a nintendo kid. I remember being 5, and watching my dad unbox the NES he bought on his way home from work one day, and being in awe of duck hunt. I've had different systems (SNES, Genesis, N64, xbox, ps2, 360) throughout my life, but never a PC.
As an adult gamer, I am no longer limited by what my family could afford; and as a gamer I want the very best experience I can afford so I built my own PC. I have a ps3 and a 360, and I hate them now; the cross platform games available are just so limiting on consoles, both graphically and in terms of size/scope of gameplay.
PC gamers should be excited for the new consoles to be released. With x86 multi core cpus, 8 GB of ram, and directx 11 gpu's, it means consoles are finally catching up to (and surpassing) what pc gamers already have in general capabilities http://store.steampowered.com/hwsurvey?platform=pc
This should mean that when games are released multiplatform, we'll get competent ports, or even parallel development. We're finally all on the same page.
