A city worth caring about.

Regions is a city-building game built in Unreal Engine 5 by Exit 5 Games. Every system from the traffic to the weather is purpose-built for one goal: a city that actually lives.

At the core of Regions is agent-based simulation: residents belong to households, live in homes, work at establishments, and make journeys across the region. Inspect a parked car and there’s a person behind it. Follow a commute and the roads you built become part of someone’s day. The aim is a city whose big patterns emerge from those small connections. Than as your population grows we use a proprietary algorithm to simulate based higher numbers based off of the agent-based simulation, so you can build a city of millions without needing to simulate every single person.

Development is aimed at a 2027 release, and it happens in the open. The roadmap is pulled live from our internal task board — when a card moves there, it moves here. Dev diaries cover the systems, tools, breakthroughs, and occasional dead ends as they happen, and community polls — on the site and in the Discord — regularly decide what gets built or written about next. The features page keeps score of what's real so far.
