Nintendo on why hardcore titles can't sell on the Wii (and a question)

[S.T.A.G.E.]

Core games don't sell on the Wii? Look at MH3 lines.

The reasons past core games on the Wii don't sell too well is because of one of these reasons, or even two or three:

1. They're niche.
2. They're new IPs.
3. They're way too short to justify the price.

1. Madworld and the conduit deserved better.

2. That is understandable.

3. How would most gamers know that its too short to justify the price?
