Bitcoin has lightning or you could use a chain with faster blocks.
That’s not true. You still only receive a license to play the game, you do not own it. Directly from GOG’s website:
We give you and other GOG users the personal right (known legally as a ‘license’) to use GOG services and to download, access and/or stream (depending on the content) and use GOG content. This license is for your personal use. We can stop or suspend this license in some situations, which are explained later on.
Practically this means you cannot resell your GOG installer in the way you could resell a physical book.
Arguably Ghostbusters (1984) is prior art for throwing a capsule and capturing 🤣
Edit: they even had a video game with the ghost trap.
I’m not really that familiar with LN, to be honest. It looks like there’s almost $500 million in the network available for transactions (source), and according to this report, there were about 6.6 million transactions in August of 2023.
Not MasterCard or Visa levels, for sure, but also not a 10 minute wait for a transaction to complete either.
