A game that can keep you playing for hours... I thought I lose interest but it's way more that just playing now. It's so cool to plan how much you need to build to balance the numbers and also making sure the folks are happy too... It's a game for anyone who likes building and expanding, planning and developing and most of all just have fun while you see your city grow! :D

Hi, I liked the game but a few things could be looked at: there are no ads to speed things up even if I'm willing to look at ads (not an internet issue), and the commercial buildings don't generate much cash so I'm always dependent on achieving the goals to get enough cash. The number of gold coins is not enough for anything, and it's hard to get those.Also while selecting buildings it would be great if you could give option of clubbing all grass types, snow types etc as different tabs

Has possibilities, but quickly becomes a game that you need to spend real money, a ton of real money, to actually play. Without spending money, you can inch, no, millimeter along for ages to earn game cash to maybe make one move in a week (spend time constantly clicking on buildings to get $, but it doesn't bank & increase over time). I'm unwilling to throw hundreds of dollars on this game, and I doubt others will either. Graphics are nice, but make play possible!
