Back in 1984 of all years, we got a computer game based on The Hitchhiker's Guide To The Galaxy. It is, to date, one of the hardest games you will ever play in your life because of two main reasons. First, it's a text adventure game, so in order to do anything, you need to type in commands (which are usually very specific). The second, and this is the bigger reason, it follows the books religiously. So if you've never read any of Douglas Adams' books or even experienced The Hitchhiker's Guide To The Galaxy beyond the film or the lackluster TV series the BBC produced, chances are you'll never be able to get past your bedroom (seen below).

This week, the BBC loaded the entire game to play for free on the BBC4 radio station's website, which you can go play right now at this link. But trust us when we tell you that if you think you're going to be the first person to breeze through this, you're not. I own and read the books myself almost every year, and I've never beaten it without cheating and having the book in front of me. So for you brave gamers who wish to conquer something so old-school that it burned down before they built the old-school on top of it, best of luck to you!
