Not many games are fully decentralized, let alone on the blockchain. Most games have the assets on chain, but the rest of the game resides on central servers.
This has far-reaching consequences for the ownership of game items. Yes, gamers own the items (NFTs), but the game publisher decides if and how you can use these!
Cryptopia is 100% decentralized without central servers. The complete game state is on the blockchain. Less critical processes are handled peer-to-peer via meshes.
There is no central authority that can change the rules around ownership of game items. Also, Crytopia is not vulnerable to DDOS attacks, does not have downtime, and is ready to be governed by its community in a DAO structure. There is no organization or authority that can take Cryptopia offline!
