AoI disks...

[Nyreal]

Do you need the CD for PSU and AoI in order to play AoI? Or do you only need the AoI disk?

What I mean to ask, basically, is if AoI is a stand-alone download.

[Ffuzzy-Logik]

AoI is stand-alone, but isn't a download, unless you mean the Xblock version, which is not stand-alone.

Standalone for ps2/pc

Download for 360 which requires the original PSU disk.
