ok... uh so I'm making a game... it's like if GTA & Apple Maps v1 had a baby
And that baby was a custom built engine that streams in OpenMapTiles (plus some other public domain mapping data) to render the entire earth as a playable open world game
Engine is all C++ with Metal (and Vulcan) renderer - which means this thing runs on ALL Apple platforms... yes even that one (ok not the watch... yet)
Right now it's just a sandbox world. No "game" - just layers and layers of systems. Earth scale procedural weather systems (rain, storms, clouds, wind, KpI, tornadoes, hurricanes, etc) which means you can see them coming from the distance and travel across the landscape in a timelapse. And every building has a procedurally generated interior.
There's also tons of vehicles, skateboarding (with skateparks), snowboarding (with ski resorts & lifts)
Also a photography mode with all sorts of fun goodies
The whole thing is a bit mad. Work's been insane right now and I wind down before bed by going through all of the work Claude has done that day, playtesting, writing up new project plans, and then kicking off the next day's projects across my 3 Macs in my house wirring on this all day with Opus 5.5 (maybe save that explainer for another crazy person Twitter screed)
Anyway, curious what you think. Now I can post my little updates here instead of blowing up all my group chats with the weird ideas I'm trying next.
My first @NewYorkAppWeek event of the week is, naturally, a hackathon! 😄
Can’t wait to see what everyone builds at the AI for NYC event with @joinpursuit

#NewYorkAppWeek has commenced - my calendar couldn’t be more packed with fun and crazy stuff!
See y’all around!
Also kicked off a racing project on one of the other machines yesterday. It’s detecting tracks and then applying a different treatment for them so they’re (hopefully) raceable and I can add ai racers and all the game logic
There’s a new sim-like physics treatment for driving on them with separate power and grip for each wheel, etc
And I added an open-wheel race car which you can tell is realistic because of how bad I am at driving it (tbf I’m on a phone sitting on a plane on the tarmac 😄)
United’s Starlink rollout started with the smallest, lowest end planes and has been slowly working up which means I have the weird experience of feeling devastated when I get on a plane and see it’s bigger and nicer 😅
Crazy busy weekend (leading up to @RevenueCat New York App Week!) so couldn’t do any actual play testing
So kicked my procedural animal life project to fill the world with more life
Needs a lot of refinement (they’re still pretty derpy looking) but with a few very flexible animal types we’ve got
Tons of birds including circling hawks, hovering seagulls, flying landing pigeons, swimming ducks/geese
Distance murmurations (big massive flocks of birds that dance around)
>100 Mammals with unique walking cycles and behaviors
Woot woot, the @DarkNoiseApp iPhone Duo update is in the the store! 😁
A few small tweaks adopting the new ArrangementView and I feel like the iPhone Duo experience for @DarkNoiseApp is pretty decent already?
Obviously will have to get more in the weeds on everything but it's a good start for _very_ little work!
Apropos of nothing, I added some of the thrusters from my lunar lander onto a sports car 🤪
(ignore the horrible sound fx, last night also started the massive project of bringing sound into the game)
If you're interested in hearing more or possibly even trying out a beta test, I set up a little form here where you can sign up. Otherwise just follow me here and I'm sure I'll keep posting as I bring new ideas into the game

Finally recorded a demo - prepare to be a̶m̶a̶z̶e̶d̶ concerned about me
Demoed this to @austnstuff after a meeting today and I can’t tell if he was impressed or concerned about my mental wellbeing 😅
yeah this reflects the mental state of the team pretty well 🤪

Hey everyone! #shipaton update regarding the next gen category - we’ve gathered all the information we need from your open source repos, you are free to close them again if you’d like to!
In terms of emails expect an update early this week still! 🚀
This one’s a big new “how do I describe this job to my family” achievement unlocked
I just saw some things I'm not allowed to talk about yet.
All I can say is that the 2026 Shippies ceremony is going to be lit 🔥
