My liege,
I think that we are all fairly much in agreement -- at least as far as Mongoose quality goes. If we weren't fans, we probably wouldn't be on these messageboards, for a start.
Still, this comment,
I consider the Mongoose teaser quite sufficient because they don't tell too much to keep the surprise, as we all know now that the contents are generally excellent.
presupposes we are aware of what Mongoose already puts out. My point of view is that a prospective newcomer may not already be aware, and could well not be bothered reading a sales pitch (and that's what the previews are) that requires him scroll down a page of fairly small print.
I don't think focusing on feats and spells should be top priority. In fact, while I think it may be worthwhile to include that information, I wouldn't know how much sales value it would actually have. It might actually be counter-productive, and beyond stressing that feat does not equal power abuse, I'm not really going to weigh in heavily on that argument. What I do think is important is distilling the previews into something that remains evocative, but is also brief and gramatically sound. Then, once the appetite is whetted, Joe Gamer can click on the "More Detail" link, and get the full flavour text.
Also, note that my opinions aren't restricted to Conan previews, but Mongoose releases in general. When I was planning on picking up Lone Wolf (my first Mongoose purchase), I started skimming after the first paragraph, then gave up completely. I wasn't interested in a history lesson on the Kai and Magnamund, I wanted to know what Mongoose had done with the Lone Wolf license. The preview text didn't tell me. When I saw the Kai class download though, and recognised the excellent job they had done, I was sold.
Similarly with Darklands, I wasn't interested in lots of flavourful text telling me the Darklands are a Bad Place. I know what the Darklands are, and how I visualise them. I wanted to know what the book offered my game. The only preview I've read completely has been Free Companies, and that was only after the topic was brought up in a thread I started.
Of course, none of us in this thread have more than anecdotal evidence for our positions. Hopefully, Mongoose can work out the best path to take and go with it, whether it be keeping things the same (with better editing :wink
or trying new strategies.
