Good city builder


This one is pretty good, it's pretty easy to learn and it doesn't pressure you to spend real world money every chance it gets. There is also plenty of opportunity, if you take your time, to increase your rank and open more building options and make gold. Also I enjoy the boost option that the paradise island game doesn't have.
Down sides: there's no storage option for building when your restructuring your city.
The buildings only go two ways, and although this saves time for designers, it would set your game apart and allow more creativity for the customers.
It's a pain to remove trees and shrubs after you buy expansion land.
I can't figure out if some structure need certain things prior to building them, so sometimes I have rando water ways, which looks odd.
Rando pop up ads. I'd pay a dollar to never see one again.
On a scale of temple runner to final fantasy tactics, this game is junk jack x.
On a scale from 1 being an A and 26 being a z this is a 2
And on a scale of Mario items, this is a fire flower.
Overall a 96% in type of game.

Not fun at all


I am on level 20. Taken a week to get there and still all I can build to get coins is farms and pizza joints. This game is a complete waste of time. Especially if you're not spending real money. At level 20 any other game would unlock much more to keep you occupied. Reality? Enter game for 3 minutes, collect your coins (never enough to build anything yet) then wait awhile and repeat. There is no real building here, just collect, wait and be frustrated with nothing to even kill a half hour of time. Nope, not for me. Try designer city and now there's something to do. Been playing 4 months, have a beautiful city and always something to do, (even from day 1). Oh, and I never had to pump even a dime into it. This is a very sloppy constructed app. I do not recommend if you're either just trying to kill time or if you are into creating a fabulous city. This is not the app for either.

The game seems ok but...


I like the overall simplicity and ease of use but I would recommend adding a boost characteristic to the various people and vehicles that populate paths. Perhaps they could add a temporary boost to the road tile itself. As is, they seem to have no effect and a city with trees instead of paths seems to profit a walk in cafe more than if certain people are walking on it's path tile.

The game does seem to be organized as “pay as you go” unless constantly resetting the clock to skip dead time that is forced on you if you don’t pay. I recommend setting your clock back a year when starting then time skip a little at a time.
