16: Still, as of yet, not releasing a true sequel to "NiGHTs into Dreams".
The Wii would be the perfect console for this, IMO
17: Mocking Playstation and Nintendo 64 in their commercials...when both systems are more fondly remembered IMO. That was a risk at the time, proved to be a bad one.
18: What hurt them in Japan, I think: no DVD player for Dreamcast, compared to the PS2.
