A playable copy of the whole Earth, built by Opus on three Macs

Charlie Chapman@_chuckyc

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.
