Umm in teory this is a good system. The problems are:

- The editor is not that easy to build Surely harder than the one for the Turn based game
- Using pre-built track components (scalectrix) will give less freedom to people to draw their own tracks..

The possible solutions are:

- Work hard and do the editor
- Dive the user not only the editor but also the exporter so they can make their own models as well..

Well in the end i think that this feature will surely be avaiable somewhere in the future

Actually i've spent all day to refactor the code so that it works with "game states" as my other project. Now it has an intro screen from where you can start the game and then exit back to the intro.
I'm always surprised how much time it consumes to do this kind of work. One usually starts coding with a single "level" hardcoded in the program.. Having the program to unload a level and reload another is a harder task than one think
