Smart contracts are the most obvious. There are a lot of applications. Like jungle said, it’s a good fit for ESCROW-type asset exchanges, but also for recurring transactions like royalty payments or dividends.

Your gaming asset example is also a valuable use. While industry inertia is indeed a relevant factor, consider: why would a company spend resources creating an object if it’s cheaper to support the framework for customers to supply their own? There’s a break-even point where it’s more profitable to outsource asset-creation and trim your staff. What’s better is the nerds who care about that sorta thing spend a lot on games.

And there are certainly others, cases where transparency is a topmost concern. Gaming seems like a fantastic proving ground for the technology: customers expect excellence, it’s a thriving and diverse market, but ultimately, a failure of the technology won’t have serious consequences in the grand scheme. If it proves secure in that arena, it might be a useful technology to incorporate into more serious applications.
