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.
There are no 3 star reviews.
