Why is SDS the game for you?

You have the freedom to do what you like, drive a box truck and deliver cargo, race a car on a track, have a demolition derby, drive an 18 wheeler. It's up to you to create the scene. You can play around with the stock content, or download mods other people have made and play with them! If you still aren't satisfied... You can make mods yourself. With a complete video tutorial series, a documentation, and example resources. You can make anything.

Planned scene/world saving features

With this, you could set up a scene, or town on a map. And play around like things in real life.
Make a parking lot of cars, or a warehouse full of truck trailers. You have the freedom to do what you like.

Open world maps

Maps that come with the game have no limits to where you can go. If your vehicle can fit, you can take it there. unless you teleport the vehicle, hehe

Advanced vehicle component simulation

Your vehicle parts can overheat, break, and have different performance properties. This provides more freedom to customize your vehicle and even fine tune certain parts, if you are into that sort of thing ;)
