That's cool, I've never played it. Though I watched one of my buddies play the hell out of it. Looked like an okay game to me.

They're the world record keepers for the video game industry. Basically, if you want to officially set a world record, you go through them. They have a strict verification process that weeds out any cheaters. They're also the official Video game hi score keepers for The Guiness Book of World Records. Right now I technically beat the top hi scores on there on both ESP Ra De and DoDon Pachi. I just have to play it on their official emulator, record it and send it to them for verification. Other than that I'm working on scores on Raiden, Fire Shark, Fantasy Zone, Elevator Action, Jackal/Top Gunner, and Super C. So I have plenty of practicing to do.
