When I first seriously considered designing and publishing a game it was in the mid-2000s and the Forge was ascendant for independent designers. It was churning out strange and wonderful games from strange and wonderful people — Vincent Baker had produced Dogs in the Vineyard, Paul Czege had made My Life With Master and Nicotine Girls. I and the authors knew what these games were about since they were built with great deliberation and starting with that knowledge. I didn’t really understand what these games were for, though. Not at the time.
(I hold no malice towards any of these people. What I will describe is not about a person but rather about a culture. Many of these folks made great games and would go on to make even greater games. I respect most if not all of them. I have learned a great deal from them. I still like you.)
Still, I very much wanted to be a part of this group, to have my work taken seriously. When I tried to engage, however, I encountered several obstacles.
First, a lot of discussion was around the Forge’s sacred texts, the essays of Ron Edwards. The relevance of these has since been minimized by most parties but at the time they were important enough to both be adhered to and yet also be debated. I read them and found them interesting where they were penetrable. At the core they implied you should be deliberate: understand what you want to do and then set all design effort towards doing that. This is pretty good advice. Be deliberate. In the details it got more contentious.

Second, the group was entrenched. There was a core group who did the bulk of the interpretation and many wrote elliptically (echoing the style of the texts) rather than plainly, alluding and planting metaphors. They used diagrams that buried meaning under a layer of more coded language, obfuscating rather than clarifying. The core group, the ones that had been there forever and helped established the culture, nodded and winked in understanding. From the outside it was less explicable but not nonsense — you just found that lacking a few years of immersion in that culture that you didn’t know the language. You were a foreign visitor with limited language skills and the locals weren’t really interested in teaching it to you. As with any local, they may not have been aware that their dialect was unusual.
Finally, the group had a gate that was well kept.
When approached to consider a new game idea, they would (almost in unison) ask: what is your game about?

On the surface this sounds like a deep question. And it is! But it’s also a way to guard the gate. The question, see, determines whether or not you embrace a top-down design methodology. And it does so unquestioningly, disregarding any other methodologies. If you couldn’t answer this then you couldn’t make a “coherent” game, which was the holy grail of the sacred texts. I’m not actually against this: I think coherence (as in tight focus, like a laser, not as in comprehensibility — people get hung up on this word unnecessarily) is a very desirable trait in a game, though perhaps I came to understand it in a more general sense than it was intended at the Forge.
I would use this question afterwards as well but that was a mistake. If I “helped” you with this phrase and you found it demoralizing, I apologize. It would be a while before I would realize what it does.
Knowing what your game is about before you design is part of a top-down design process: you decide and define what you want to accomplish (your requirements) and then you start designing mechanisms that all further that goal. You start with your intention and you develop your realization, drilling down into greater detail as you go. You develop mechanisms that serve your purpose.
This is a really good way to design things (especially very large and complex things). It’s not a bad thing to teach this methodology and expand on it.
But when I was asked that question and couldn’t answer, I felt rejected. Like I couldn’t answer what my favourite colour was at the rope bridge of doom. The gate was shut (and it doesn’t matter if this was the intent — this was what happened regardless of the intent). And so I bounced off the Forge and while I made some effort to understand it, I was never welcome and I never performed the necessary genuflection to be accepted. I could mouth the words but I didn’t believe.
That’s because there are other ways to design. There really are. You can start with a cool setting idea and start planting mechanisms in it that you dig and slowly assemble a game. And then refine it. Along the way you may well discover what the game is “about” and at that point you can continue to refine it, gradually focusing it on the target. Coherence does not only emerge from one design methodology. I often wonder if that metaphor can be pushed further — it seems like the top-down Forge methodology produced great accuracy: the games hit the nail on the head when they work (I had so many play well one night and fall flat the next). They did what they were supposed to do, usually. By contrast, other methodologies may be better at precision: whatever they do, they do it reliably again and again.
Anyway, I always felt rejected by the Forge. In point of fact I bounced off the gate so hard that it would be wrong to say they rejected me — you have to have some kind of deliberation, some assessment in order to reject. I was never given enough attention to reject. I just ricocheted.
