Our verdict on Megaworld
6.3/10MegaWorld suits long-time blockchain gamers and curious newcomers who like city builders and want to see how AI agents might live in an on-chain world. Its main strength is a seven-year history and a stated plan to keep existing maps and assets. The main caveat is that the product is mid-rebrand to MCPOLIS, and fees, audits, team and token details are not published on the homepage. Verify everything through official channels and risk only small amounts.

What is Megaworld?
MegaWorld, originally MegaCryptoPolis, launched in early 2018 as one of the first dApp games. The project says more than 50,000 players built three virtual cities over seven years, linked by an on-chain economy.
The homepage now announces that MegaWorld is becoming MCPOLIS. The game is being rebuilt so autonomous AI agents can work and live in the city alongside people, using the Model Context Protocol. The project says the same city maps and players' assets are carried forward.
Over the years the project has added features such as unit NFTs, crafting and a free-to-play delivery mode, and expanded to new chains. The homepage does not publish details on fees, audits, team or tokenomics. Readers should treat the new MCPOLIS direction as work in progress.
How Megaworld works
MegaWorld is a city builder where land and buildings in the virtual city are owned by players through blockchain records. The project describes the world as player-governed with an on-chain economy, so game rules and ownership are tracked on public ledgers.
According to the project, it opens a new realm every two years on a different blockchain: Ethereum in 2018, TRON in 2020 and BNB Chain in 2022. The three cities are connected through the shared economy.
The MCPOLIS rebuild adds a new layer. Using the Model Context Protocol, a standard way for AI systems to connect to tools and services, autonomous AI agents are meant to work and live in the city next to human players. The same maps and player assets are said to carry over.
6 features
Key features
01
Seven-year track record
The game launched in early 2018 as MegaCryptoPolis, making it one of the oldest running blockchain games. Its homepage says more than 50,000 players built three cities over seven years.
02
On-chain city economy
The project describes a fully on-chain economy that connects its three virtual cities. Assets and city activity are recorded on public blockchains rather than only on a game server.
03
Multi-chain realms
Per the project's posts, a new realm opens every two years, with earlier ones on Ethereum, TRON and BNB Chain.
04
AI agents as players
The rebuild uses the Model Context Protocol so autonomous AI agents can take part in the city alongside human players.
05
Asset and map continuity
The project says the existing city maps and players' game assets carry over to MCPOLIS.
06
Past game modes
Press listings show earlier additions such as unit NFT minting, crafting and customization, and a free-to-play delivery mode called Express.
Pros and cons
What we like
- Operating since 2018, with a long history compared with most blockchain games.
- The project reports more than 50,000 players and a fully on-chain economy.
- Stated commitment to preserving existing city maps and player assets through the rebrand.
- A clear new angle: AI agents playing alongside humans through the Model Context Protocol.
- Has expanded across Ethereum, TRON and BNB Chain, showing it has adapted over time.
Watch out for
- The rebrand to MCPOLIS changes the product direction, and the AI-agent version is still being rebuilt, so what players get today is unclear.
- Fees, in-game costs and token economics are not published on the homepage.
- No audit reports, team details or licensing information appear on the homepage.
- A game economy tied to land, units and a token can lose value, and earlier play-to-earn payouts are not a guide to future returns.
- The project runs across several chains (Ethereum, TRON, BNB Chain), which adds bridging and wallet complexity.
- The homepage points to a new brand site, so documentation and support may be split between the old and new names.
Megaworld fees
The homepage does not publish a fee schedule. Actions that happen on-chain carry network fees on whichever blockchain the player uses, and those vary with network conditions.
Any in-game purchase prices, marketplace fees or token-related costs are not stated on the homepage. Users would see them inside the game or in the project's official documentation and announcements.
Is Megaworld safe?
The homepage does not link security audits, name a team or describe how assets are custodied. Because the game runs on public blockchains, players generally hold their own assets in their wallets, but smart-contract bugs, phishing and fake migration sites remain real risks.
The rebrand is a point to be careful about. Scammers often imitate renamed projects, so only use links from the official site and verify any contract addresses there before signing a transaction. Game assets and tokens are volatile, and you should only spend what you can afford to lose.
6 steps
How to get started with Megaworld
- 1
Open the official site and read the MCPOLIS rebrand notice to see which version of the game is live.
- 2
Check the project's official channels for current instructions on joining or migrating existing assets.
- 3
Set up a compatible crypto wallet and keep your seed phrase offline.
- 4
Confirm which blockchain the current realm uses and fund the wallet with a small amount for network fees.
- 5
Review any contract addresses or token details only on official channels before approving transactions.
- 6
Start with a small amount while you learn how the city economy and AI agents work.
Who Megaworld is for
This is for players who already own MegaWorld or MegaCryptoPolis assets and want to know what the MCPOLIS change means for them. It also suits people interested in blockchain strategy games and AI-agent experiments who are comfortable with wallets and the risks of in-game economies.
Megaworld FAQs
What is MegaWorld?
MegaWorld is a blockchain city-building game that launched in 2018 under the name MegaCryptoPolis. Players build and run virtual cities inside an on-chain economy. The project describes itself as one of the first dApp games.
Is MegaWorld now MCPOLIS?
The homepage says MegaWorld is now MCPOLIS. The game is being rebuilt around the Model Context Protocol so autonomous AI agents can work and live alongside human players. The project says the same city maps and players' game assets carry over.
Which blockchains does MegaWorld run on?
The project's own posts say a new realm opens every two years: Ethereum in 2018, TRON in 2020 and BNB Chain in 2022. This is why the game spans three chains rather than one.
Does MegaWorld have a token?
Search listings reference a MEGA token and a token sale announced before the game's debut. The homepage does not describe the token, so check the official MCPOLIS channels for its current status before buying anything.
Do I keep my assets after the rebrand?
The homepage says players' game assets are preserved under the new brand, along with the city maps. It does not give a step-by-step migration process, so follow the project's official announcements for instructions.
What does it cost to play?
Fees are not published on the homepage. Blockchain network fees apply to on-chain actions, and any in-game costs would be shown in the game itself.
Is MegaWorld safe?
No game is risk-free. In-game assets and tokens can lose value, and smart contracts can have bugs. The homepage does not link audits, so treat any money you put in as capital you could lose.
