Aha, if only it were so simple. I'm making them. I am, using a game though, you are correct. But everything you see in that picture so far, was placed and moved, and set up. MC, the Assault Rifle, every plant, and even the water, were all placed down. I use Gmod to make stuff. Gmod was originally a sandbox game but overtime people got inventive with it. They started ripping game models and porting them. With enough craftiness, so long as you have the resources, you can make some nifty pictures.
