Modern Urban Simulator Co-op Game

I’m putting together a modern-day, realistic city-scale simulator built for both single-player and seamless co-op. Picture a lively urban sandbox where you can pick up almost anything, load it, sell it, and use the profits to grow a company that must keep a stream of quirky AI customers happy. Item rarity, user reviews that influence gameplay, and plenty of tongue-in-cheek moments for streamers are all core to the vision.

The project hinges on a big map that feels believable yet fully interactive: alleys to explore, warehouses to manage, and delivery routes that change dynamically. Because we’re aiming for a realistic look, every prop needs proper physics and tight collision so hauling crates—or accidentally dropping them—feels authentic and entertaining.

Multiplayer is just as important. I want drop-in/drop-out online co-op with synced inventories, shared objectives, and a review system players can trigger in real time. The end goal is a vertical slice that proves these pillars:

• A playable urban district with streaming-friendly performance
• Core pick-up / load mechanics, including physics-based handling and item rarity tiers
• Basic company-building loop: earn, expand, serve customers, collect feedback
• Networked co-op supporting at least two players, inventories fully synced
• UI for the in-game review system that updates on the fly

If you have solid experience building simulator mechanics, networked gameplay, and realistic environments, let’s talk about pipeline, engine choice, and milestones. Show me samples that highlight physics interaction or multiplayer systems, and we can dive straight into scoping the first build.
