Theme: Science & Technology Category: Strategy Game

0 views 0 plays

Blue Sky City makes the player a mayor who has to clean up the air. Each month the player splits the budget between public transport, bike lanes, city parks, smokestack filters, a burning ban and site dust control while keeping residents on side. Twelve cities with different personalities (traffic-choked, factory towns, a misty valley, a peatland city with drifting haze) force players to read the pollution-source bar, the weather forecast and the 20-month PM2.5 chart. Every city is proven winnable, a "Did You Know?" card covers PM2.5 and the air quality index, and the game is easy to re-skin with the mascot, colours and lessons of an ordering brand or environment agency. Try it right here below, then picture a game like this featuring your brand’s logo, characters and prizes.
