I heard this game came out in Japan,but never the USA. What was it about?
Navi's Trackers is essentially a party-based fetch quest.
As I recall, you went around talking to pirates and getting stamps.
The reason it never came to America is probably the difficulty in translating, as it used Voice Acting.
I've heard as well that they decided not to port it because it used CEL-shaded 3D graphics, which Nintendo believed the American market was quite displeased with at the moment.
that was at the moment...
