A lot of driving and operating heavy machinery has been a part of the game from the beginning, but this is the first time that players will get the chance to drive a giant machine on their own. You will have to build houses, for example, and this will be one of the ways to do it. 

Story line

The game starts with a road-building challenge, where you have to build a road in a village and make it passable for cars. As you progress, you will encounter different challenges, like moving the road from one place to another, or building a house.
