Released in Japan on september 26, 1998.
For me the "arcade booms" are on this timeline: Space Invaders > Pac-Man > Street Fighter II > DDR
Probably one of the most influential games of all time, with Beatmania before this but still this was THE mainstream rhythm game that changes everything. I just cannot imagine how many PS1 DDR dance pads were sold, original or bootleg, Also it was the road for so many japanese and european dance artist (RIP Captain Jack).
So many good memories. time flies so damn fast.
