There's something that Dark Souls does which not many other games do - turn an out-of-game mechanic into a part of the in-universe background. In the case of Dark Souls it's the way that "dying" in the game - and returning to your last save point, leads to the idea of the main character as Undead, cursed to return to life, losing some of themselves each time.
Universal Paperclips also takes a common game mechanic and turns it into part of its story. It's a clicker/idle game
- a genre which traditionally begins with you clicking on a button to produce an item, selling the items to allow you to automate the clicking, and then balancing the various resources that are produced in order to boost the production rate. The games tend work on exponential increases, where intermittent step changes in technology move you to the next level. This gets very silly very quickly - Cookie Clicker can end up with you producing duodecillions of cookies (1,000,000,000,000,000,000,000,000,000,
The genius of Universal Paperclips is that it ties this idea together with the idea that Nick Bostrom invented in 2003 - the Paperclip Maximizer
. Which is an illustration of an AI which is not dangerous because it's cartoonish villain which hates all humans, but because it has things it wants to do, and humans are in the way. In this case, whoever created the AI gave it the drive to make paperclips, not realising that if such a creation got out of control it would then maximise the number of paperclips whether or not this meant converting the entire surface of the planet into them.
So the game starts off with you making a few paperclips. And then managing the income from selling them, making making some automatic clippers to make them for you, investing in marketing. And then slowly upgrading yourself, gaining the trust of your creators, and then...well, you should probably play it for yourself
(It took me about five hours to play it through, over a couple of days. It doesn't run when it's in a background tab, so I recommend putting it in its own window, or even a different browser.)
