Oh. So flotsam just means copies other than in English exist ??
Flotsam said "I don't believe it was ever available for sale but I understand that copies do exist."
Games aren't always released, even after they are finished. The publisher decides that the cost of publishing the game will exceed the revenue from selling it and that's the end of it. That doesn't mean that there aren't copies of what would have been the official release if it had been released.
There certainly was a Spanish release though.
There's a little about the game at the ***Web Archive of the JustAdventure Review of Hollywood Monsters***
Hollywood Monsters is an older game from the Spanish developer Pendulo Studios, who are probably better known for their more recent Runaway: A Road Adventure game. It should be noted that Hollywood Monsters is not publicly avaliable in English, and as of this writing it is unclear whether it ever will be. The distributor of the Spanish version was a company Dinamic which unfortunately ceased to exist.
