No revenue estimate for PSN — its rating/review counts don't calibrate to sales the way Steam's do. The Steam version is estimated at $5.6M — a different platform, not this one.

Mini Metro

In Mini Metro, you take on the task of designing the subway layout for a rapidly expanding city. Your city starts with three stations. Draw routes between these stations to connect them with subway lines. Commuters travel along your lines to get around the city as fast as they can. Each station can only hold a handful of waiting commuters so your subway network will need to be well-designed to avoid delays. Eventually your network will fail. Stations will open too quickly. Commuters will crowd the platforms. How long the city keeps moving is up to you. Key Features - Compelling, constructive, hectic, relaxed gameplay. If that makes sense. - 3 game modes: Normal for quick games, Endless for stress-free play, and Extreme for the ultimate challenge. - 20 real-world cities to design subways for. Each has a unique colour theme and set of obstacles. - Supports up to 4 players. Build with your friends and argue over the best design. - Trains! Did we mention them yet? 1-4 players 200MB min
