I don't see much point in that comparison, to be honest. Nintendo has far more money to spend, a build-in platform for pushing their own content, and a need to produce software to sell their console. Not even close to the same starting point.
And as far as comparing game budgets between third-party and first-party efforts, first-party titles do not have the same overhead. It's not the same situation and people need to stop acting like it's not going to be more expensive for a third-party publisher to produce the same content.
Besides, you can't much fault companies for Yakuza or Monster Hunter when Nintendo has developed over 11,000 Mario-themed games in the same timespan.
