The BBC released what was designed to be an easy to use, themed game editor back in October of 2016.
"Today, the BBC is challenging teenagers to get creative online with the Gold Rush Game Maker, which allows users to create their own gold rush adventure games, based on the three part series Operation Gold Rush with Dan Snow on BBC 2.
"Similar to BBC's award winning Doctor Who Game Maker, this will allow users to create and publish adventure games featuring the real-life adventurers from the forthcoming series about the 19th century Gold Rush in the U.S."
