Bombjacker, I do not know of a similar concept before Beatmania was released. I think i twas the first one. And aagin, it came from Japan. US developers have zero creativity, I don't think tehy could ever come up with an original concept. They didn't even do it in the Amiga/C64 days methinks, most original concepts came from Europe back then. Americans tend to stick to what is popular.
I agree with Shatterhand a little bit. Today's kids will say 'the good old days of the PSX' in a few years, but even that way I still think games from teh golden era were the best. It REALLY was the golden era of videogames. Not everybody knows Defender or Joust, lemme tell you
