Speed-dreams works great.
While this is a great start of a project, the developers need to get realistic and include some error handling. Most of the cars act somewhat realistically, except for the plethora of changes that have been made to their settings (mu at 2.6? wtf?) to work with the simulation engine. Creating a car or robot is an exercise in futility as there is very little documentation and the developers constantly refer back to the source. There is no user support, searchable forums, or active chat room associated with this game, as for some reason the developers constantly use a javachat and mailing lists. Open source development has changed, and these developers don't realize it yet. They need to become more open and realize that most of a fan base will not know C/C++, that most people expect useful error messages, and that users want to be able to communicate with other users through an easily searchable interface. It could be great, but the developers have shrouded themselves so far away that they can't communicate with the fans anymore. Wouldn't even bother downloading until the 2.0 release.
Excellent game, good graphics and very realistic. However, it takes a little time and training to learn how to control downforce and traction else the car can start dancing in every sense, it is certainly a bug to fix. There is not much information about the network mode and there is no list of servers to connect to play online, you can only connect to a known IP address, the one for example of a friend who host a party. Many cars and tracks, possibility for the brave, to create their own but this involves knowledge skinning, 3D, softwares like Blender, Gimp, Inkscape ... creation takes a long time, about 80 to 120 hours to create a circuit but you can also start by modifying existing ones. Too bad this game is not better known by the Community, the DEV Team has difficulties to recruit good contributors in the long term but gradually it evolves. I tried to register on the forum unfortunately I can't find anywhere the answer to the question of confirmation (what is the most hated animal of the Speed Dreams Community) !? I have not found that either contact someone, the Facebook page is no longer updated for several months. I'm here in hope to find a contact. It is perhaps this difficulty to join the Community that prevents amateurs to participate.
