After some technical problems and last minute bugs, Sony has launched the Open Beta for PlayStation Home. The program icon will automatically appear in your XMB, but will require a download to begin. The program will then reserve about 3 GB of hard drive space for future downloads as you explore the virtual world.
Users in America should be able to check out the Uncharted and Far Cry 2 game spaces, but these areas have not been localized for Europe yet.
Additionally, the "Diesel and Ligne Roset content will be added next week at the same time as the Red Bull Air Race."
I was able to download the client, but could not connect to the servers at this time. Let me know if you have more luck connecting.
