Opensc2k.com: SimCity 2000 in the style of OpenTTD

New graphics and an OpenTTD-inspired interface. Build neighborhoods, connect transport and utilities, and manage the finances of a growing city.

Compatible with good old SimCity 2000™ save games (.SC2).

OpenSC2k is a playable native remake of SimCity 2000™. It keeps the isometric city, zoning, infrastructure and municipal decisions of the original, with new artwork and a desktop interface inspired by OpenTTD. The game is written in 100% C code.

Your job goes beyond placing buildings. Decide where people live and work, connect districts across difficult terrain, supply essential services, and keep construction and operating costs within the city's budget.

Zoning and city growth

Lay out residential, commercial and industrial districts, with light and dense zoning. Connect new areas to the networks they need and watch buildings develop from foundations and framing into finished homes, shops and workplaces.

Transport networks

Build roads, highways, railways and subways. Use bridges and tunnels to cross water and hills, connect surface rail to underground lines, and add stations, bus depots, airport zones and seaport zones as the city expands.

Utilities and public services

Choose power sources, run power lines, and build water networks with pumps, towers and treatment facilities. Provide police and fire protection, hospitals, schools, colleges and recreation alongside the infrastructure that supports growth.

Budgets and city policy

Set residential, commercial and industrial taxes, adjust service funding, and compare income with running costs. Borrow or repay bonds, consult advisors and choose ordinances that affect the city and its finances.

Terrain and disasters

Generate a new landscape or reshape existing land with raise, lower and level tools. Rivers, coastlines and hills influence where you build. The disaster tools include fires, floods, tornadoes and earthquakes; disasters can also be disabled.

Old cities and new saves

Open original SimCity 2000™ .SC2 cities and see them with the new graphics. Save ongoing games in OpenSC2k's native .sc2k format, or begin again with generated terrain and a different plan for the next city.

A compact toolbar, a large map, and windows that open over the city. The layout takes its cues from OpenTTD, with scalable controls and movable panels for the information you need.

Construction tools, map controls and reports sit above the map. The date, current simulation state and treasury stay visible along the bottom, leaving most of the screen for the city itself.

The graphics are four times the original resolution in each direction and use 32-bit RGBA. New building designs, roads, railways and landscapes keep the familiar isometric map, with distinct architecture for residential streets, commercial districts and civic landmarks.

Construction is visible on the map, too: new sites progress through foundations and framing before the finished building appears.

Detached homes for residential neighborhoods.

Larger apartment blocks for denser residential districts.

A neighborhood shop with a striped awning and street-facing windows.

A glass office tower for the commercial skyline.

A factory with rooftop equipment and industrial workspaces.

A civic landmark with a clock tower and formal entrance.

A dedicated building for the city's health services.

Fire protection for the surrounding city.

A wind turbine as an alternative source of city power.

A futuristic arcology with a tall glass-covered habitat.

No line of OpenSC2k's own code was written by a human.

The remake's game code, original building artwork and this website are made with AI. A human directs the work and reviews the results.

OpenSC2k took about 3½ weeks to build, including the time a human spent maintaining the agents with GPT-6.1 Sol.

Existing third-party libraries and resources retain their original authors, credits and licenses.

OpenSC2k is an alpha version. The game runs on macOS and Windows, with ongoing work on the simulation, artwork and interface.
