Schimid made a thread about 2 years ago about this, and back then it went through a long beta test that was free for all, then went pay to play for a long time.
This past week it went free again, so anyone that's interested in any music games (similar to DDR but you're not using your feet in this), just check it out at
www.o2jam.com.my
if you want to play, you'll need to set up a free account at
www.e-games.com.my
There is an international (meaning non-malaysian) tournament being run in mid-January that's open to anyone that would like to participate. go to
www.o2jammer.com if you want to register for that. (i'm helping run the tournament so i won't be competing)
There are still bugs in this game, but it gets addicting if you like music and hitting things to the beat of music. At least it's free again.
