"The way we make games is we’re very careful. We’re very thorough. We’re very detailed. We take a long time analyzing the different parts of a game… almost to our detriment. Almost too careful. I think the need is there for us to make decisions more quickly, weigh the risks [and] see what the payoff is."
I say they should take all the time they need, it's better to deliver a quality product, than to release a bunch of sub-par games. What Nintendo really needs to do though is hire more developers.
