I think this is a great point. And honestly have to say this is the crux of it all. Fundamentally games should be fun. If they are not fun then it simply doesn't matter. Having said that there are many arcade machines that are a tonne of fun. I think the arcade machine can be reinvented and reward players (because of composability which simply cannot exist with the protocols implemented in existing arcade machines).
Viewing post in Blockchain and gaming can they co-exist?
Composability between protocols (exists on Solana for example) => This means any inputs can be combined together and worked on a different protocol in the solana network to earn yield. The yield can be instantly realised(after it has been collected) and the inputs returned back to the users = > With this a user who played can be picked at random (or it could be a high scorer) => They receive a digital good (realised from this yield (which can be harvested at any time). This composability is exists in this digital economy and it can be used to give more value to players
