People use the word fun a lot when talking about role-playing games. What do we mean by that? Which elements of a game are responsible for people having fun? That is, which elements that we can find in the rules compared to the elements we can find at the table such as props, people, decoration, lighting, music. I’m going to assume that “having fun” results players in coming back session after session and I’m going to assume that this can be explained by behavioral psychology. It seems like a good starting point to me.
A long time ago, I was interested in a [PlayByEmailGame play by email game] called Atlantis. I decided to learn how to program and translate the game into German. I ran [GermanAtlantis German Atlantis] for a long time. I learnt to code, I learnt about Free Software, Emacs, Geocities, HTML, web pages, mail servers, shell scripts and many other things.
Atlantis had regions, units, ranged weapons, melee weapons, a simple resource economy, and so on. It also suffered from a design flaw: as your faction kept growing, preparing your turn turned out to be a chore. It took hours if you had thousands of units!
Later, I wanted to write a new game. It’d be limited to a single person per player. It would have magic items such as swords. The swords would record all the owners that had ever owned it. Improving the sword would need ingredients. This would be the economic part. I thought about it, made some notes, and after a while I discovered that the resulting game turned out to be bland and boring.
What had I missed? To bring the topic back to role-playing games: what is it about the games I don’t like?
I think the key here is that what brings me back to the gaming table is the same thing that makes slot machines addictive. It’s called the variable ratio reinforcement schedule: a reinforcement schedule in which the number of responses necessary to produce reinforcement varies from trial to trial, according to Wikipedia. Apparently, the variable ratio reinforcement schedule results in a high and stable rate of responding with the greatest activity of all schedules. I guess that also explains why I’ve been playing Pinball Arcade on my tablet for so many hours. It’s a simple two-button game. How can it be so addictive? It’s the variable ratio reinforcement schedule: sometimes, when you’re skilled and lucky, you amass incredible awards and it makes you want to come back.
In terms of role-playing games: some monsters are tough, some monsters are pushovers. Some treasure is great, sometimes no treasure can be found. Sometimes the lucky dice save your butt, sometimes treacherous dice kick your butt.
Every player wants to win fights, find loot, gain levels and all that. But for the players to experience maximum reinforcement, for the players to be into the game like addicts, for them to come back week after week, for them to exhibit the behavior we would describe as “they must be having fun” the referee should use a variable ratio reinforcement schedule. I’m claiming that unbalanced encounters and a high variance in treasure found result in a more addictive game.
