From the Store description:
Township is a unique blend of city-building and farming experience for your tablet and phone! Share your vision of a perfect place to live in! Harvest crops on the farm, run processing facilities and sell goods to develop your town. Explore the mine to get resources and sail to distant islands for exotic products. Open cafes, cinemas and other community buildings to encourage social life.
Are you ready to build your dream? Township is completely free to download and play. Some in-game items can also be purchased for real money, however this is optional and not required for an EXCEPTIONAL GAMING EXPERIENCE.
I'd take issue with the 'Exceptional gaming experience' part, in that the mechanics aren't that different to a dozen other games in the same genre. Credit to the developers for putting some work into the status numbers at the top of the main playing screen, which (for a change in such a port) aren't too small to see properly. And the logistics of building and farming and eating and receiving orders and building and farming and harvesting (etc., you get the idea) do all hang together. It's just that there's nothing here that actually is.... exceptional.
Yet again I find myself calling for a cap on in-app-purchases, to avoid clumsy, unintentional expenses (or perhaps being messed over by your teenage kids who know your PIN). If you've played any freemium-heavy game in the last year or two then you'll know exactly how all this works. Mainly in favour of the developers.*
You can grab this in the Store here if you still want to give this a go, it's around a 90MB download.
* Yet again, in my opinion the perfect place for in-app purchases is for topping up a commercial game with a low purchase price. So a £2.29 cost with no impediments to play and then in-app-purchases of up to, say, £10 to buy extra 'stuff' in the game to customise the experience.
