We have a group where we are planning to develop some games using those punks, so yes, it is very interesting. Also many projects on Hive Engine are complex and have centralized logic, because coding Hive Engine is not easy nor intuitive and not simple at all, but since Punks on Hive vanilla is so simple it runs completely on Hive Engine.
I am usually skeptical about Hive Engine because of the centralization issues, but since I have coded for Punks on Hive I saw it is decentralized so I like it and I support it. The devs could make the website open source though, so people could learn from what has been done.
