Do you have sometimes a good idea for a new, exciting layout or modification of an existing track? But you don't have enough time or ressources to realize your dream? What about a open database where trackbuilder from all over the world could get half-finished tracks working? For all btb-supported games, e.g. rFactor, GTR 2, RaceOn, RBR and many more Import/export of btb-projects is really easy, all you need is the whole project-folder (including the xpacks). Ok, the huge number of big xpacks would blow up the filesize... But I guess you'd need only "special" xpacks, because nearly everyone has the most uploaded xpacks already installed. + there won't work builders on the same track at the same time + we won't get 10th times the same times from different user + no more competition between the different games ("why does the track isn't available for xxx?") So, what do you think about?
