I also sometimes miss the PS1 era, I wouldn't call it the old days either, though. The old days systems to me are NES, SNES and Genesis mainly. What still makes me remember the PS age was all those new exciting games being released. It felt like there was a wave of high quality games that had astonishing graphics for their time and experimented with the then still new 3D elements. And it was also the time RPGs thrived most, following Final Fantasy VII's release.
