When it comes to first introducing someone to a new wargame, a quick-start guide is essential for getting up and going. Quick-start guides offer a gradual start into a particular wargame, giving players just enough rules to get them gaming without overwhelming them with minutiae. So what do you need to consider in order to write a good quick-start guide?
The first thing you need to do is consider your audience. How much wargaming experience do they have? Are they familiar with your game and its conventions or just wargaming in general? A good way to strike the balance between an audience that knows your game and one that doesn't would be to include a 1-2 page blurb (with plenty of pictures!) that introduces the reader to your game world. It will serve to draw in those who are unfamiliar with your game world, but those who are already familiar can easily skip it. Likewise, if your quick-start guide is bundled with multi-part plastic miniatures (as most of the quick-start guides from Games Workshop are, for example), including an assembly guide is always helpful.
A quick-start guide should start small and build up so that players learn the rules in manageable chunks. There's two main ways I've seen this presented:
Blocked out overviews are great for covering all aspects of the game rules that a new player might be curious about. They take up relatively little space, too (the Battle For Black Reach overview is a two-page spread), meaning that you can pack your quick-start guide with other content such as model assembly guides or painting tutorials.
Conversely, linked missions are better for learning the actual rules since they start players with the absolute rules basics (usually moving and attacking) and then build up from there. For example, the Battle For Macragge quick-start begins with movement and shooting and then adds assault rules in the third mission. The second and fifth missions also expand the shooting rules, adding flamer and blast templates.
Once you've decided between a blocked-out overview and a linked mission list, the next thing to do is consider layout.
The best quick-start guide in the world won't get eyes on it if it's not laid out well. So how do you properly lay out a quick start guide? There's two big things to keep in mind:
Once you've decided how to frame your content and decided on layout, the last thing you need to consider is how much content to include. You want your quick-start guide to stand on its own - that is, a prospective player should be able to pick up your quick start guide and, by the time they've read/played through it, they should be able to play an actual full gameplay loop of your game without necessarily consulting the rulebook.
Consider your gameplay loop. What are the main phases of your game? Ensure that each phase is included somewhere in your quick reference guide. The best way to do this is to slowly build them into subsequent loops, where each loop expands on the previous loop. So the first gameplay loop might be movement and shooting; the second might be movement, shooting and close combat; the third might add on morale tests, too. The goal of this is to use steadily-increasing gameplay loops to gradually introduce your game's concepts to your players so that they are not overwhelmed. For someone new to wargaming, having to deal with movement, shooting, close combat and morale checks for multiple units can be dizzying - much better to start with as few models and as few concepts as possible.
Decide how many mini-gameplay-loops you need to introduce your gameplay concepts. Usually, you'll have as many mini-loops as you have concepts, with the end goal being that the last mini-gameplay-loop is in fact a full gameplay loop - each of the concepts of the previous loop has been included in it.
Include a hook. Once players finish your quick start guide, their immediate question is usually "what do I do next?" Including a section that answers these questions is a great way to keep your players engaged with your game.
So, here's how you write a good quick start guide for your next wargame:
