The racing kit looks like a cool and easy setup for anyone who wants to try to make a racing game… except it’s got no cars!
I don’t have any specific inclination to make such a game myself, but I am currently attempting to put together a little diorama-type thing with the default assets, and making a diorama out of the space kit and the castle kit is easy because those kits each have structures, characters, and vehicles, but I can’t really do anything cool with the racing kit as is because it’s mostly just track.
I respectfully petition for at least one or two car models in the racing kit.
