Hi . ..The improvements are stunning...it has the best train track of your city islands games .its very easy to install in your city..the only complaint I have is this...there are very few buildings to build on one island.for example ..you can buy 2 gas stations. then they go on gold. this happens to most of the buildings..one is then forced to buy another island.won't you please sort this out..make more of the buildings available...and not put them on gold so fast...and have more gold available

This game is super addictive, but the simulation needs serious improvements! Currently, there is no traffic, no jams, and cars just drive right through the middle of buildings. The city feels dead because citizens only wander on the streets and never enter houses, restaurants, shops, or parks—plus, no one ever parks a car. There are also no police patrols, no day-night cycle, and no weather changes. Developers, please fix these issues to make the game truly amazing!

City Island 6 is hands down my favorite app game! It has so much content to enjoy, frequent updates, fun events, and absolutely beautiful graphics. This is the longest I’ve ever played a mobile game, and I still love coming back to it. The in-app purchases are affordable and reasonably priced, but they’re absolutely not necessary to enjoy the game or make progress. There’s so much to do without spending money. The developers have done an amazing job keeping the game fresh and entertaining!
