If you have Xbox Live Gold, you will be one of many allowed to download the Beta for Phantasy Star Universe starting this Wednesday and Thursday. Players wil be able to beta test online for a week, ending October 18th.
After that, it will be $9.99 for a month or $49.99 for six months when the game ships to stores on October 24th. (Oh, and you have to still pay for the game too..even if you beta test). Crummy way to get you addicted, I know.
