Player controls any vehicle that is designed to move in two or more dissimilar environments (air, land, underwater, space, etc.) with ease.
Name variations: multi-environment vehicle
The first video game about Multi-environment craft was released on June 30, 2002.
Amphibious vehicles should not count as they only float on water besides moving on land, similarly airplanes that move on land should not count (part of their standard operation during takeoff and landing at the very least).
A hovercraft or similar does not count for this as land & air vehicle, but can count as on land and on water vehicle.
