The Act is an interesting arcade game developed by Cecropia, that was never officially released, but the few cabinets that were made were eBayed and some local arcades and collectors were able to get them. A video review of The Act can be found at The Game Grin Arcade website, in which they play their cabinet that can be found in Utah.
As they wrote in the video description:
It’s a real shame that they pulled the project as while it is a game that is along the lines of something like Dragon’s Lair, it is far more advanced than DL, Space Ace or any other FMV game that has come along that I have played as while those early FMV games promised interactivity they didn’t truly deliver on that promise while The Act does.

The Act is helped by it’s unique control scheme which is very simple to understand and use. All you have is a knob that you turn during gameplay to affect what happens in a scene. The further you turn the knob the more intense the reaction of the main character Edgar gets. […]
Because The Act was canceled it is very rare – only 40 units were made and of those only about 10 actually made it out onto eBay.
Thanks a lot to Luke for the contribution!
