Not sure if this was supposed to be in the imports section as this game has an American counterpart, but it is originally Japanese. It's a rhythm game made by Konami, whom Harmonix of Guitar Hero fame pays licensing fees to for using a musical instrument gaming peripheral. This in addition to the style of game where you match keypresses to music. Anyway it came out for ps2 over a decade ago(in Japan), and the one version the USA received came out in 2006 just titled Beatmania. I thought I'd share the game with anyone who hadn't heard of it before, uber replay value and difficulty... which I guess makes it more rewarding to become proficient at.
