Maybe a Vehicle/Flying/Open world kit. That has all the basics for a car, plane, boat, train pack actually be a better name. Something that is geared towards a game like EX: Farming Sims, Boat Sims, Tanks, Plane games, etc etc, a game that main focus is a vehicle instead of a character. Great idea and thing you doing though, I’d be sure to buy these off the Market Place for a fair price! Especially if they came with Tutorials/Videos.
