This is a long game and quite enjoyable. I bought it from Realore, and didn't have to purchase coins. They are slow in adding up, but you can get them. By using the coins to finish tasks you only shorten the game, but you do use them.
The graphics are great and colourful. The processes of creating goods can be slow but there is much more to do while waiting. Lots to do and lots to create and many deliveries to make.
I am now on the last leg of the journey with all tasks completed.
You really need patience to continue with this game, unless you buy the coins, then you just need cash.
