Quoted from Ferret:
I don't know the answer; that's up to Andrew. My personal preference would be to offer a basic guide to gameplay (perhaps on YouTube, as was done for Full Throttle), but NOT publish our entire rulebook. For me, a big part of the joy of a new game, whether on location or as a home owner, is the discovery process: finding the tricks to boosting scores, finding the right combination of features to stack, learning that how you do on this thing influences that thing over there. Publishing the full rules would short-circuit most of that discovery experience.
I couldn't disagree with this more. You know that just because a rulebook exists, people don't have to read it. I get that some people want to explore on their own and don't want to know anything they didn't figure out themselves, but others don't have the time or the energy to fully explore all the permutations of different play tactics, especially if they're not good enough players to full execute what and when the opportunities arise. I'm somewhere between these two extremes. I'd like to save the "surprises" but get the details on play strategies.
I don't have the time or attention span to learn what impacted what fully on my own. But I will read rulesheets and try to execute those strategies. If you want to be surprised by everything, just don't read them.
I can tell you for sure, that I have gotten SO MUCH more enjoyment out of games after reading rules and strategies. Back when I first started collecting I would print off the rulesheets from pinball.com and read about all the modes and scoring tactics. This made the games so much more fun. More recently, I have a Hobbit and didn't know what I was doing. I was seriously thinking about selling it. Now that I've read the rules, I'm really loving it.
By not releasing rules, you are hurting the people that want to read them and learn strategy in that fashion. On the other hand, by releasing them you give people the choice. I don't read spoilers online for shows I'm watching. Players that like the suspense can do the same thing here.
