you can issue challenges to your friends and they can come to your arcade and get one free play on the machine to match or beat your score, which is neat, but I don't think anyone cares about it. you might like some of the Konami arcade releases, so look those up, but it's nothing something worth investing. I think the Konami arcade releases are more expensive than the usual $3 for a game but I'm not sure.
