That doesn’t really change the question, though: the Tomb Raider developers don’t need an NFT to do that, and any other company isn’t going to spend much of their money giving something for free to a handful of someone else’s customers. Why spend time on that instead of, say, charging $10 for the homage DLC which gives them actual revenue and from a much larger number of people?

For example, how many of those NFTs would have been lost or stolen — and do you want to tell potential buyers “sorry, nothing we can do about it - blockchains mean no margin for error!”
