I’ve been reading Steward Woods’ Eurogames, a book that aims to lay out an overview of the origins, design trends, and culture around German-style board games. There’s a lot of interesting stuff there, but one thing in particular that stands out is the discussion of how different types of games use randomness.
In board games in general, randomness is optional, but people view it as having a certain kind of value, in that it prevents pure skill from being too dominant (so a wider range of people can enjoy the game) and it can add replay value through random variety. There’s a spectrum of randomness, with games of pure skill like chess on one end, and games of pure chance like Chutes & Ladders on the other, and most games living somewhere in the middle. That alone is a stark contrast to RPGs, where with a few exceptions, people tend to regard randomness as simply non-optional.
There are several different things that divide eurogames from tabletop games of other design traditions, but one of the big ones is not the presence of randomness, but rather the ways in which games use randomness. Wargames seek to simulate war, and war is unpredictable. Competent generals do what they can to improve their chances of success, to tilt the die roll in their favor, but the realities are such that it makes sense that there’s a random component to the success or failure of whatever you attempt to do. D&D took up this approach to randomness, where you choose a course of action and then see if it succeeds, presumably from its wargame antecedents, and (partly but not entirely due to D&D’s massive influence), it’s become deeply ingrained in hobby games in the English-speaking world in general, including RPGs, and that in turn has greatly influenced video games. In contrast, by and large eurogames use randomness to determine what options you have in front of you, but don’t leave you to roll the dice to determine if they succeed. In Catan (to pick a well-known example) you roll dice to see what materials the players accrue, but there’s no roll to see if you can successfully build a city. Once you meet the requirements, you can get a city, and that’s that.
