One of the more complex games on the Ethereum blockchain is MegaCryptoPolis, a decentralized city building game where players purchase virtual plots of land to gain influence in a community built on the blockchain. Let's go over how these ERC-721 tokens work and how players are hoping to earn a profit. If you want to learn more about unique digital assets, try this guide to crypto collectibles.

How Is MegaCryptoPolis Different From Other Ethereum Games?

MegaCryptoPolis is not the first dapp to involve ERC-721 tokens. In fact, it's not the only city simulator on the blockchain. What makes it different from Fair City is that it uses MetaMask, and all transaction are paid in Ether, so it doesn't involve its own ERC-20 currency. While these are unique assets, they are different from something like Factbar because of the amount of gameplay involved. You can purchase a plot of land, wait for it to go up in value, and then sell it, but most players are looking to earn a profit through the redistribution of funds that happens in the game's tax system. That makes it closer to idle games like Ether Shrimp Farm or something like Gandhiji, where those who invest heavily at the start can earn a profit from those who get into the game later. It's too early to say how much can be earned from MegaCryptoPolis, so it's best to only get into this if you plan to play the game for a while.

How To Play MegaCryptoPolis

In Depth

MegaCryptoPolis is a sophisticated city simulation game that exists on the Ethereum blockchain. Players own and develop blocks of land and participate in a complex virtual society, earning Ether based on their influence in the game. While still in its early stages. MegaCryptoPolis has laid out an intricate system that has some excited by the possibilities of earning a profit through clever gameplay.

You may have noticed that MegaCryptoPolis looks a little like the classic Sim City franchise, where players build a virtual city and see it grow and change throughout the years. Think of it like a group Sim City game, where players interat with one another to build one big city. You can purchase individual plots of land and construct buildings on them, either in the hopes of selling them to other players, or as part of a strategy to further your standing in the city. And thanks to blockchain technology, you really own your plots of virtual land because of a standard called ERC-721.

Let's take a step back and explain exactly what ERC-721 is, and why it allows you to own land in a virtual city. Most people are familiar with Bitcoin and Ethereum, cryptocurrencies that rely on blockchain technology. The use of a decentralized ledger allows users to verify transactions without the need for a central authority. Ethereum is notable because it allows for the creation of decentralized applications, or dapps, that support the trading of alternative assets on Ethereum's blockchain.

Beyond Bitcoin and Ether, there are many other types of crypto coins available. Often companies will issue an "I.C.O.," where they sell coins that represent a stake in their business. Most assets available on the blockchain are like Bitcoin and Ether in that they are fungible, meaning all coins of a certain currency are the same. If you have two Bitcoins, and you plan to sell one, it doesn't matter which one you sell because they are worth the same amount.

Often companies will issue an "I.C.O.," where they sell coins that represent a stake in their business.

But some assets are unique, or non-fungible. ERC721 is a standard for smart contracts on the Ethereum blockchain dealing in assets that are not all the same. A popular example is Factbar, online representations of facts that are researched and verified. When you claim a Factbar, it goes through the site's smart contract and the transaction is backed up by the blockchain.

Since Factbars are unique, if you own one, no one else can own it at that time. If someone wants to buy it, they have to get it from you. Every Factbar has its own unique value, and highly-desirable Factbars are therefore very valuable because they are rare.

The plots of land in MegaCryptoPolis are ERC721 tokens just like Factbars. They are one of a kind, and each has its own value and price. Based on your situation in the game, the price of your plot of land could go up, and you could sell it at a profit. And because this is a game, there are many in-game decisions that affect the value of your plot of land.

And because this is a game, there are many in-game decisions that affect the value of your plot of land.

Blocks of land exist in seven by seven fields. When you purchase an unclaimed plot of land, the price of the surrounding plots goes up. And when those plots are purchased, part of that payment is redistributed to the other block owners in the surrounding field. You can also purchase a district, larger areas that comprise the greater game area. These are sold through auction, and if you own the district, you receive part of the purchase price of all blocks within, and collect taxes from the owners.

There are different types of blocks. Some have resources, and some can have construction on them. You can construct different types of buildings on your land, and if you own several connecting blocks, you can build a mega building. Upgrading costs Ether, but the more you upgrade, the more influence points you'll have.

Influence points determine the amount of Ether that will be redistributed to you through taxes. Part of every transaction is collected to be given out to district and block owners. The more influence points you have, the more Ether you will receive. Part of the strategy of the game is to gain enough influence that you will collect passive income from daily transactions.

Like a lot of Ethereum-based games, players are trying to get in early on MegaCryptoPolis because they think they can earn a profit. But remember that the creators aren't just handing out free money. In order to earn a profit, you have to outplay others in the game.

But remember that the creators aren't just handing out free money.

Those who are looking to invest in an asset might find this a bit too involved. But those who want an intricate gaming experience will be pleased at the level of complexity here. MegaCryptoPolis is still just getting out of the gate, but it's the most advanced city simulator on the blockchain so far.
