One year ago, I stepped down from my operational responsibilities and COO role to become an Ambassador for @TheSandboxGame.
👀 Since then, I've stayed closely connected to the company's progress through regular conversations with the leadership team.
👍 A year later, I'm more convinced than ever that the direction The Sandbox Studio is taking represents the next generation of game creation and the metaverse.
🏗️ Here's what's coming:
▫️ A mobile-friendly, web-native platform powered by an AI-native open game engine—not just another LLM wrapper.
▫️ Accelerated onboarding for the 10,000+ creators currently on the waitlist, starting in August 2026. The waitlist will soon be a thing of the past.
▫️ Public launch in Q4 2026, with monetization available from Day 1 in both fiat and $SAND.
▫️ LAND owners will be able to earn revenue without being creators themselves by acting as publishers, hosting creators, and sharing in the revenue they generate.
▫️ A new live, interactive 3D isometric world map to explore.
▫️ Improved content discovery with featured placements to help outstanding experiences reach more players.
▫️ More open communication with the community, with feedback gathered on Discord ahead of releases.
▫️ Faster product iterations, with new releases shipping at an almost weekly cadence.
The long-term utility and demand for $SAND will grow by empowering creators to build engaging games with strong retention loops, seamless player acquisition across the platforms of their choice, and the freedom to design their own in-game economies and shops.
It's exciting to see this momentum continue. I'm proud to support the team in my Ambassador role and can't wait to see what creators, LAND owners, and the community build together. 🚀
An NFT as a movie ticket 🎟️
A villa in the Hills now costs the same as a movie ticket. Every holder gets a front-row seat as we build this film together 🎬
Mint yours 👉 opensea.io/collection/hollyw…
🎬 Hollywood Hills Villa mint update.
You told us the price wasn’t right, and we heard you. On top of that, a fake collection went live pretending to be us. So we stepped back, rethought the launch, and came back with this:
🎟️ Same price as a movie ticket ($16). Except this time, you’re part of the movie 🎬
🏡 Public mint opens TODAY at 10AM ET
💰 0.00666 ETH
📅 Open until December 28, that’s 66 days from now
🔄 Trading is open
Mint at @opensea opensea.io/collection/hollyw…
🙏 To our early WL supporters: you can choose a refund of the price difference or a full refund. [open a ticket in discord]
⚠️ Beware of fake pages and collections. Only mint through @hhillsofficial links.

What do stars do ? A question beffiting the studio system as well as the greater cosmos @hhillsofficial @arthurmadrid @borgetsebastien
Creating new IPs has been my passion for 15+ years. What excites me most is bringing communities along for the journey, letting them participate in building these worlds and even share in their success.
🎬 Who says virtual worlds can’t become games, movies, or both?
💪 Proud to support Hollywood Hills, a cosmic horror film expanding into its own universe, featuring 3,000 Villa NFTs illustrated by Steve Scott and even a real-life bus tour through L.A.
A new way to create, finance and experience entertainment together. Check it out 👇
A mystery will be revealed soon 👀
One of the five estates got a surprise visit… Clues are everywhere, you just need to know where to look @hhillsofficial @arthurmadrid @borgetsebastien
