Yesterday I played the demo of Phantasy Star Portable, and I was impressed. The graphics are amazing and everything looks about as good as Crisis Core.
However, unlike Crisis Core, the voice acting is appalling. I was wondering if it would be possible to take all the audio from the Japanese version, and use it to replace the audio in the American version. Granted, I haven't played the original, but at least then if it's bad I wouldn't know it. I know you can change music, so this doesn't seem entirely outside the realm of possibility.
