Hi there guys, I'm new, but I already played all Phtantasy Star™ games, but now, I found this, I want to play online but the registration site http://billing.playsega.com/ doesn't work (I think beacuse playsega.com is under manitance), how can I get my Game ID to "throw" myself to PSU™ world?
It sounds to me like you are trying to play the PC version of the game online. If I am correct, then unfortunately the servers for the PC version were taken down a couple years ago, sorry
Right now the only online PSU servers being run by Sega of America are the ones for the XBox 360 version.
If you're going to play the xbox 360 version you can pick a psu copy of the disk at an near by video game store for about $15 or less. Or you could download a copy off of games on demand for $20 once that happens, you have to download Aoti dlc which is free of charge, than go on the game and go to online mode and it'll ask you if you want to buy a guardians license say yes I believe you pay $10 and first 3 months you get, I don't know if that changed and after the 3months you pay $10 every month.
If you are trying to get the pc/ps2 servers to work they have been shut down.
