Ground-Based Simulators · Precision Physics · Real Worlds
A collection of passion-driven vehicle and lifestyle simulators. Started with an open-world recreation of Kish Island, built with Unity. Now expanding into racing, island living, and radio-controlled vehicles — all by one person, for the love of it.
Each project is a separate world — a different vehicle experience, a different place, a different philosophy. All connected by the same passion for ground-based simulation.
Motorsports · Custom Grounds · WebGL
Ground-based racing on custom Grounds. Precision vehicle physics, deep car customization, and a simulation-grade race engine. The foundation for ATG Pardis.

Read DocsATG Simulator is a solo passion project by Dan. No studio, no publisher, no deadline. Just a long-running obsession with building places worth driving in, grounded in realistic vehicle physics.
It started with ATG Kish in 2017 — an open-world recreation of Kish Island in Unity. That project never shipped, but it built the knowledge and the conviction that this kind of thing is worth pursuing. ATG Racing comes next, laying the physics foundation that everything else will inherit.
The name "Around The Ground" says it simply: all of this is about vehicles on the ground. Racing, cruising, drifting, or just going nowhere in particular across a beautiful island. The ground is the constant.
Every ATG project runs on serious vehicle physics. NWH Vehicle Physics (customized), Pacejka 6.2 tyre models, realistic drivetrain and suspension. No arcade floatiness.
ATG Kish was based on actual Kish Island. ATG Pardis captures the spirit of the Caspian coast. The goal is always worlds that feel like somewhere, not just somewhere to race on.
No release dates invented to fill a page. No fake timers. If something ships, it ships. Updates go on X and the blog. This is built because it's worth building.
ATG updates happen on social media and the dev blog. Come see the progress, grab free shader downloads, and follow the long road toward finished simulators.
