The best The Sandbox alternatives in 2026

Megaworld

Games: Metaverse · Ethereum, Tron, BNB Chain

MegaWorld, formerly MegaCryptoPolis, is a blockchain city-building game that launched in 2018 and is now rebranding as MCPOLIS, rebuilt so AI agents can play alongside humans. Its long history is a strength, but the new direction is still taking shape.

Nifty Island is a 3D social game where players build and customise their own islands, run quests and earn the ISLAND token. It has a real product and token, but the token is small and illiquid.

Derby Stars is a horse racing game built on Polygon in which players breed, train, race and trade NFT horses. It is aimed at NFT collectors and play-to-earn players who accept token and asset price risk.

Upland is a real-world city-builder where players buy, develop and trade virtual properties tied to actual street addresses. It is a game-first economy with a fiat on-ramp, and results depend on how much time and money you put in.

TCG World is an Ethereum-based metaverse game centered on exploration, building, NFT collectibles, and virtual land. Its token and marketplace add crypto features, but current access and operating details are unclear.

Decentraland is an Ethereum-based virtual world where people can attend community events, create experiences and use MANA, including around NFT land. Its appeal depends on finding active content and communities, while token, NFT and smart-contract risks remain.

World of Dypians

Games: Metaverse · BNB Chain, Sei

World of Dypians is a blockchain-based MMORPG and metaverse game with its own WOD token, staking pools and multichain support. Interest is real, but audits, fees and tokenomics are not clearly published.

IM

Imvu

Games: Metaverse

IMVU is a long-running 3D avatar chat and virtual goods platform that added a VCORE token for its NFT marketplace and creator economy. The platform is established, but the token side is unproven and its price pages show very little value.

SE

Secondlive

Games: Metaverse · BNB Chain

SecondLive began as a BNB Chain metaverse with avatars, spaces and creator tools, and now describes itself as an AI-driven world model platform. Activity signals look weak, so treat it as a speculative, low-liquidity project.

Wilder World is an open-world metaverse game built with Unreal Engine 5 and tied to an NFT-driven economy and the WILD token. The sources describe an ambitious game with a steep price decline, so the main takeaway is to separate the game from the token.

NE

Next Earth

Games: Metaverse

Next Earth was a map-based metaverse where users bought 10m x 10m plots of virtual land. A project update says it has no active team or funding and has shut down.

Somnium Space is a blockchain-based virtual reality metaverse with a native utility token called CUBE. The sources reviewed describe a social, persistent VR world, but they leave out the details needed for a full assessment.
