I would gladly take part but why do I need Discord. I don't like it (cause too much words). My WIP map does manipulate vehicles: They become means of transportation cause the map is big and nice. They can be refilled with a own non game breaking LUA logic, fuel destruction (for more frequent refilling), maintenance like tire replacement and car washes (also non game interrupting) are planned. But maybe that's not what the contest is meant for? Also my project is very time consuming (I am working way over a year now) and such a short contest situation can (again) hardly be fulfilled by me . It is interesting anyway .
What would fit the theme of vehicle manipulation better then... Powerups! So here comes my entry: https://www.beamng.com/resources/powerups.33601/ A gameplay addition with a focus on making powerups very customizeable, interactive with each other and its effects synchronizable
