Exactly this. There’s been an obsession with tech laypeople execs to put blockchain tech into anything because it’s what they perceive to be the cool hip thing to do, but it’s a just tool with certain benefits and should only be added if and when it makes sense.

What could you do with a blockchain in a video game? Well, you could make in game assets into tokens that can be traded outside of the game, creating a secondary market for things that is entirely outside of the game publishers control. Why would you want to do that, though? It might be attractive for MMO gold farmer types, but the MMO game makers themselves are going to want to run in the opposite direction from such a thing. Maybe an Steam achievement trading card scheme? Again, why would anyone do that, though, when the system Steam uses works just fine and there’s no risk of things getting out of control as Valve has full control over the marketplace.

Honestly, I struggle to think of a single other real use. That doesn’t mean that there’s no use for it, but it’s definitely not something that should just be crammed into any product, let alone video games.
