I get what you are saying about this being a half assed expansion style release but for PlayStation 2 owners, this is the first shot at this game for them. Had they released this on Dreamcast, or released the Dreamcast version of DOA2 on PS2, then released this, I would whole heartedly agree with your sentiment.
At least they added something extra with this release. Sega is well known for doing jack squat between ports and still asking full price each time.
