I got my first copy back on the Dreamcast and PS2 and played the hell out of it. I wrote my first USB drivers for the Trancevibrator around 2005, also.
When Infinite came out I still played it quite a bit (outside of the context of making that video heh), and it was like riding a bicycle. A couple of minutes of getting used to it again and I was back to near 100% on everything. :D
If you haven't played Polybius or Sayonara Wild Hearts, I can highly recommend them - they are both games that stroke their fingers gently across the same places that Rez tickles.
Still wish any other Mizuguchi game did it for me as much as Rez. Never got to try Child of Eden, Every Extend was good, Lumines and Tetris Effect were ok but just not quite the same. I think Rez had that combination of perfect timing and place.
It may also be a magical working. I am dead serious here.
