I’d have the renewal cost for the 55-60 year extension somewhere around the $2B mark. There would be _very_ few pieces of work that would be valuable enough to spend a few billion for 5 years of additional protection. I’d structure the system so that Nintendo could probably afford (but it’s be painful) to blanket buy the 5-10 year extension for every title it publishes. But the 10-15 year extension would probably be an existential bet for the company, and the 15-20 year extension for every title they publish would be enough to bankrupt the company. The fees should be painful enough that you renew specific works that are still economically productive, but impossible to simply renew everything.
