The Two Types of Random in Game Design



From critical hits to random encounters, and from loot boxes to procedural generation, video games are stuffed to bursting with randomness. In this episode, I look at the way randomness is used in games – and why some forms are more contentious than others.

  • I think a good example of output randomness is tabletop gaming yes it’s different but the fact is that rolling dice to attack a monster in dnd is the same as trying to attack an alien in xcom

  • WoW BFA patch 8.3 is basically the Xzibit of randomness. They put in rng inside of your rng so you can rng while you rng. Anyone who has played it knows what I'm talking about. Its really a prime example of how to implement randomness in a bad way.

  • Don't even forget how RNG is sometimes a very big fun factor, in for example Hearthstone, where sometimes players intentionally build and play RNG decks just for shits and giggles.

  • Only example of input randomness that is frustrating is the circle in games like pubg where if the zone forces you to run across an open field is pretty annoying

  • As someone whose first ever Terraria run was graced by a pre hardmode Drax, I can confidently say I thought Terraria was much easier than it actually was for a long time. RNJesus has never given me such luck since.

  • 2:00 I have some objections!
    Minecraft worlds aren't infinite, they are very very large.
    You can see that for yourself by typing in the following command:
    /tp @p ~200000000 100 ~200000000
    You will see the edge of the world. If not, repeat the command, eventually you will be there.

  • The two kinds of randomness:
    Good randomness: When all outcomes are desirable, but there's a variety
    Bad randomness: When you randomly get either a "good" result or a "bad" result

  • The "game lying about the true probability" for output randomness is super prevalent in Wizard101. Almost every spell has a chance to fizzle out and not execute, which is based on which school the spell is from. Fire school spells are usually in the 80%-85% hit range, but in my experience there's never a time that it fizzles more than once every ten tries.

    I think it makes sense considering the combat is pretty simple and was originally designed for kids, who would understandably get super frustrated by continuously losing due to randomness, whether or not they understand percentages to begin with.
