it's not for noobs
It's not a waste of money at all, if you can read japanese and have a japanese IP-Adress

FUN
It would be fun if I had broadband... (mazbe microsoft would do something?)

Service is for japan only
If you're outside japan or if your ISP in Japan issues you a foreign IP, you won't be able to play this game because they're filtering foreign IPs. There is no point in buying it unless you're just wanting it as a collection.
