AnimAction is one of the Vectrex titles that requires the light pen accessory to operate. The light pen pack-in cartridge Art Master, only had rudimentary animation capabilities... AnimAction takes animating your vector based artwork to another level. An interesting fact about the AnimAction cartridge is that it is not an any of the the aftermarket multi-carts because it had extra memory built in to save your artwork, making it a more desirable program cartridge for your Vectrex collection. let's face it... there is something cool about seeing your own art moving about on the screen of a gaming console that is over a quarter century old! This is one of the software releases where GCE broke out of the "games only" mold and endeavored to make more interactive and educational programs for this awesome vector based platform.
