Seven Deadly Sins NFT Adventure Shuts Down on November 11 — as Web3 Gaming Funding Quietly Doubles

A licensed anime experiment ends after one season
MARBLEX has set a closing date for its Seven Deadly Sins NFT Adventure: the service ends on November 11, 2026, at 11:00 (UTC+9), the company said in a service termination notice posted on X, pointing players to a Medium announcement for details. The shutdown lands roughly three and a half months after the game's second season — licensed from Kodansha, the Japanese publisher — launched on Immutable on July 30, and about three months after MARBLEX reported a sellout of all 15,000 NFTs in the collection by August 11, with Demon Meliodas supply capped at 1,000. The notice said nothing, in the reporting so far, about NFTs still out on exploration or about Demon Meliodas NFTs staked for MBX — the exact questions players are now asking in the open, and the exact questions any shutdown announcement should answer first.

The numbers behind the closure
The closure does not arrive in a vacuum. A September report found MBX sitting about 99% below its 2022 listing price, and MARBLEX's parent finances under strain: as of late June the company reported assets of about 30.5 billion won against liabilities of 83.8 billion won, a semiannual net loss of about 2.1 billion won, and total equity of negative 53.3 billion won. MARBLEX says its Web3 business continues along three lines — expanding MBX Store and MBX Pay, Web3 publishing for outside projects, and an all-in-one virtual asset financial gateway — and it points to recent wins elsewhere, including Meta Toy Dragons Saga reaching No. 1 on the Google Play Store less than 10 days after its August release, and an October partnership with Microsoft on game publishing and AI. But the company is candid that growth at home is not coming soon, citing multiple regulations in South Korea that make significant growth difficult at this stage.
The wider November calendar — and a funding pulse
November is crowded with Web3 gaming dates, which is why this shutdown reads as a calendar story as much as a single-game story. Blast Wheels targeted an iOS and Android launch on November 2, expanding its Web3 racing title into free-to-play mobile with in-app purchases and a plan to allocate a portion of settled revenue toward $WHEELS buybacks and liquidity; BBG is set to launch on November 4; Cashbox's refund and transition window closes on November 12; and the Four Ancient Civilizations enter hibernation with core gameplay suspended on November 13. Against that churn, October's industry funding data tells a split story: the web3 gaming industry logged $192.5K across 45 tracked capital events in October, up 104.8% on the previous month — a doubling from a very small base — while the JRPG Gaming Index, a market-cap-weighted benchmark of 20 crypto-gaming tokens, closed at 12.10, down 1.14% month-over-month, and Axie Infinity: Origins led monthly news coverage with 73 mentions. Money is still moving, but it is moving cautiously, and mostly to infrastructure and proven titles rather than new token launches.

What players should take from this
The lesson of Seven Deadly Sins is not that licensed IP fails in Web3 — it is that a game's token economics and its parent's balance sheet matter as much as its brand. A sellout mint in August did not save a service whose token had lost 99% of its listing value and whose operator was carrying negative equity. For players, the checklist before committing to a Web3 game stays the same one Zimbuck set out in our beginner safety guide: https://zimbuck.com/blogs/800/How-to-Buy-Your-First-NFT-Safely-Wallets-Marketplaces-Gas — check who holds the treasury, what happens to your items if the servers stop, and whether your NFTs live on a chain you can actually use elsewhere. And for the sector, the honest read is in our November outlook: https://zimbuck.com/blogs/839/Web3-Gaming-s-November-Gauntlet-Abstract-Migration-Deadline-New-Launches — November was always going to be a month of deadlines, and the first of them has now produced its first casualty.
