It doesn't have to be an RC game, just one that allows you to design your own off road track. We're looking for ways to test more than one layout without having to build it and then discover we don't like it. VRC is too expensive to be stuck playing on road only. I started racing in on road, and loved it, but the local track was shut down by some jerks. The only racing we can do now is off road, because it's more popular, and there are several tracks nearby. We have a track in a friend's very large yard, but we want to change the layout. It would save a ton of time and effort if we could design a layout and test it before we build it.
