In my spare time, I enjoy playing some games with my private tabletop gaming group. We’ve recently been playing Shadowrun, a cyberpunk story driven role playing game with exciting lore, but a massive and complex collection of rules. The standard solution for determining whether a player succeeds or fails at something is by rolling success dice. You add all relevant stats together and roll a number of six-sided dice equal to your sum, and every five or six you get is called a success. The problem with this process is that it takes a very long time. With high stats, a player could spend up to 30 minutes determining whether or not he hit what he was shooting at.
In my first iteration, I didn’t bother adding any instructional context. This was primarily to finish it quickly so my friends could use it as quickly as possible, but also because it wasn’t necessary. It was only intended for the five players in my group, all of whom I was speaking to in real time so I could just tell them what to do.
