In 1996, a US studio called MediaX began working on a videogame inspired by George Orwell's 1984. It was called Big Brother, and you played a member of the resistance called Eric Blair (which was Orwell's real name), breaking into and sabotaging government installations across 12 levels with hundreds of puzzles. Yes, they were turning Orwell's classic dystopian novel into an adventure game.
MediaX's Big Brother was canceled in 1999 or 2000, possibly because the licence had expired before the game could be completed. It had been shown at E3 in 1998, with a release date of September that year and a $30 price tag, but at some point after that it was delayed and subsequently thrown down the memory hole.
