This is where Bitcoin finally hits its stride and begins to shine - showing us the next level of abstraction of digital rarity, and you decry it for yet another centralized video game? If the CryptoKingdom servers shut down, your assets are gone.. If the Pepe team were wiped clean from the Earth and the entire game were erased... you would still have your Pepes and a new game would begin to be built around them.
That's the power of a decentralized asset. You are trying to get us excited about the video game equivalent of fiat, when something far better already exists. I do hope CryptoKingdom gets ported to the Aeon version of Counterparty, when it one day exists. I would definitely be interested then.
Crypto Kingdom needs a decentralized setup, otherwise it wont take off imo. One possibility would be to clone jl777's komodo setup for his instantdex which launches in a short while, which afaik allows for decentralised trading.

The pepe meme is nothing compared to the rich detailed design of Crypto Kingdom as a full virtual world of assets and social networking opportunities, but I agree it needs decentralised asset trading so players can control their own assets. If that is achieved (decentralised trading and private control of keys), then Crypto Kingdom could become one of the largest crypto projects to date.
