Best Play-to-Earn Games of September 2021, Then and Now

Play-to-earn, usually shortened to P2E, described blockchain games where players could earn tokens or NFTs with a market value outside the game. In 2021 the model spread quickly. Players often earned in-game assets by completing battles, breeding creatures, farming resources or finishing quests, then sold those assets on marketplaces for cryptocurrency.

The core idea was that in-game items were recorded on a blockchain, so a player could in principle hold, trade or withdraw them. Many games also used a second token for rewards or governance. This was a major change from traditional games, where players rarely owned anything they could sell outside the publisher's platform.

The model also carried risks that were less visible in the hype. Earnings depended heavily on token prices, which could fall sharply. Many games needed a steady flow of new players to keep rewards valuable, and some were closer to investment schemes than to games. Understanding those mechanics is the key to judging any title from that period, and it remains the right lens for reading P2E games today.

Rankings of a single month age quickly. A list tied to September 2021 is best read as a snapshot of what drew attention then, plus an account of what became of those games. Lists from that era were often built on player counts, token trading volume and community activity, and those figures change daily.

When you look at old P2E lists, check three things: the date the ranking was published, the metric it used, and whether the games still run. Many 2021 favorites have since changed their models, merged, moved to other blockchains or stopped active development. A title that ranked highly then may now have far fewer players or a different token.

The goal of this guide is practical. It explains which types of games were prominent in 2021, what happened to the model, and how a reader can evaluate a game now. Current player numbers, token prices and reward rates should be checked on the game's own site and on independent data trackers, because those values are not stable enough to state here.

Several kinds of titles defined the P2E wave of 2021. Axie Infinity, a battle and breeding game built around creature NFTs, became one of the best-known examples and drew large player numbers in several countries. Other games focused on virtual land, mining or collectible cards.

The category broadly included:

• Creature battle and breeding games, where players raised and fought NFT creatures.
• Virtual world games, where players bought land and built or earned inside a shared map.
• Mining and resource games, where players gathered in-game materials for tokens.
• Card and strategy games, where collectible cards had trading value.

Several games in the modern P2E conversation are continuations or relaunches of these early ideas. The Sandbox and Alien Worlds are examples you can still examine today, along with newer titles that followed the same blueprint. Judging them now means looking at the current version of each game, not the one that dominated headlines in 2021.

Alien Worlds is a play-to-earn metaverse built on the WAX blockchain. Players mine resources and take part in a shared world, earning the TLM token and NFTs that represent in-game items. It is among the games most often cited when people discuss the early P2E era, and its design leaned heavily on mining mechanics and community involvement.

What to check today:

1. Whether the game is still active, using its official channels and independent activity trackers.
2. How rewards are generated, and whether they come from new players buying in, from token emissions or from fees.
3. What the TLM token is used for, and where it trades.
4. Whether the costs of entering, such as NFT land or tools, are worth the expected return.

Alien Worlds shows the strengths and weaknesses of the model clearly. Community ownership and open markets are real features. But returns that depend on token prices and continuing player inflow can change quickly, and a reader should not assume past reward levels will return. Treat any reward figure you see online as a moment-in-time number and confirm it before deciding anything.

The Sandbox is a virtual world built on blockchain infrastructure, with ties to Polygon and Ethereum. Its token is SAND, and players and creators can own land, build experiences and create assets as NFTs. It belongs in the P2E conversation because owning land and building things for others to play can produce income, but it is not purely a game that pays for playing.

Metaverse games of this kind work differently from battle or mining games. Income often comes from creating content, renting or selling land, or operating an experience that other players visit. That shifts the risk from grinding for rewards toward building a useful product and managing land costs.

The Sandbox has also been developing creator tools, including an AI-assisted game engine that is in beta according to current reporting. Tools like this can change how people make content, but they do not guarantee income. Before buying land or assets, check the current price history, marketplace fees, the number of active visitors and what the developers say about future plans. Ask whether the value depends on a single platform, a single token, or a community that might move elsewhere.

Aavegotchi is an NFT collectibles game with the GHST token. It began with a design that tied the game to DeFi, where players staked assets and used lending protocols as part of the gameplay. Over time the project has moved to new chains and expanded its tools for players and builders, and reports indicate it is moving to Base.

This type of game blends collecting, staking and yield mechanics. The attraction is that an in-game asset can earn returns through staking, but each layer adds risk. A smart contract issue, a lending market problem or a fall in token price can affect the whole structure.

When reviewing a game like this, look beyond the name. Ask which protocols it depends on, whether those protocols have been audited, how the game's own contracts have been reviewed, and what happens to your assets if you stop playing. Compare the expected return against the cost of the NFTs and the gas fees for each action. A simple check is to write down the worst case: if the token falls sharply and the game loses users, what remains of your position? If that answer is uncomfortable, the game may not suit your budget.

The P2E boom reshaped expectations. Many early games depended on a steady inflow of new players to fund rewards. When new player growth slowed, reward values fell, and token prices often followed. Several well-known titles lost most of their active users, and others changed reward systems or added paid features.

Some common changes include:

• Reducing token emissions so rewards are smaller and more sustainable.
• Shifting from pay-to-enter models to free-to-play access with optional purchases.
• Placing more emphasis on gameplay quality, so players return for fun rather than income.
• Moving to newer blockchains with lower fees.

These shifts matter because they show that P2E is not a fixed category. A game that paid heavily in 2021 may pay differently now, or not at all. Many newer titles place less weight on earning and more on entertainment, which can make them easier to assess honestly. Read the current reward design rather than the marketing, and check how the model has been revised over time.

A good evaluation is more useful than a ranking. Use the following checklist before you spend time or money on any P2E game:

1. Gameplay: Would you still play if no tokens were paid? If not, the game may depend on rewards rather than design.
2. Activity: Check active players, transaction counts and whether updates are still shipping.
3. Token: Learn what the token does, how much supply exists, how new tokens are released and where it trades.
4. Costs: List every entry cost, including NFTs, gas fees, marketplace fees and withdrawal costs.
5. Security: Look for public audit reports, bug bounty programs and a record of responding to incidents.
6. Team and governance: Identify who runs the project and how decisions are made.
7. Exit: Confirm that you can sell or withdraw assets without special permissions.

No single factor decides whether a game is safe or worth your money. Weigh them together and be skeptical of any claim that a game guarantees income. Many projects rely on promises of future growth. Where a figure matters, such as APY, TVL or token price, use a current tracker and note the date of your check.

Readers who want to look at P2E-style games today can start with a few categories rather than a single winner list. Big Time is a free-to-play multiplayer action RPG for Windows PCs that includes NFT collectibles and its own token, aimed at people curious about Web3 economies. ImmutableX is a web3 gaming platform on Ethereum, where the IMX token supports fees, staking and governance, and it is relevant to readers who want to understand the infrastructure behind many games. Warp uses NFT starships that earn daily credits across several chains. Robots.Farm is an on-chain collecting game where players open crates, hatch eggs and stake robots, but its reported TVL is very low and it has no listed audits, which should make any reader cautious.

When comparing these, separate the game from the token. A game can be enjoyable while its token is volatile, and a token can gain value while the game stays small. Keep a record of what you spent, what you received and what your assets are worth on the day you check. Only use money you can afford to lose completely, and never treat game rewards as income for planning.

Blockchain games involve wallets, token approvals and third-party marketplaces, so basic security matters. Practical steps include:

• Use a dedicated wallet for gaming, holding only the funds you plan to use there.
• Never share your seed phrase or private keys with anyone, including people claiming to be support staff.
• Read each transaction and token approval before signing, and revoke approvals you no longer need.
• Type or bookmark official addresses yourself rather than following links from messages or social posts.
• Be cautious of giveaways, airdrops and offers that ask you to send funds first.

Also check your local laws. Crypto assets and in-game tokens may be regulated, taxed or restricted depending on where you live, and rules differ by country. If a game involves wagering or chance-based prizes, the same rules apply: check local laws, confirm you meet the minimum age, and remember that gambling carries real financial risk, so set limits before you start. Keep transaction records for tax purposes where that applies.
