1/64 scale cars were meant to be played with. The Gaslands miniatures rules allow these cars to be used as a part of a structured game.

Of course 1/64 scale cars can also be gamed dynamically (the cars do roll) when used in combination with "car playsets". The fun is in inventing fantasy worlds in which these cars are a major feature. Here are some ideas:

Playsets can be grouped into distinct "Zones".
A mythology can be created about each "Zone".
Vehicles can be sorted into distinct categories.
The vehicle packaging often includes vehicle specifications.
