The next SimCity is being built with an impressive engine called GlassBox. While the engine is designed to impressively and realistically display something akin to a real-life city, it was also “built to be moddable.”

“We’re huge fans of our modding community,” said creative director Ocean Quigley to a GDC audience. “We know modding is hugely important to our community. We know the reason why people are still playing SimCity 4 ten years later is because the modding community has kept it alive. GlassBox is built to be moddable, but beyond that we haven’t announced anything.”
