Presto - I really like the art-laden link. May not improve sales but it sure does kick allot better.
Blue Devil - Great website. I am envious.
Now on to the "Observation of PDF Prices" --- which is not a press release but an invitation to discussion (or at least I take it that you wanted to talk about it).
This is all IMO.
I think we are just seeing differing attitudes toward the business of publishing reflected in marketing techniques. Ronin Arts and LPJ are going for a smaller investment with multiple products to build a company name. The success or failure of a single product is less important than the broader goal of name recognition and sales. Nothing wrong with that - in fact it is smart business.
The Big Bang books are something unusual in that they own the specialized market that they are in - so I do not think we can use them as a good example. I will use XPR, who up until this point they have been more concerned with producing comprehensive and semi exhaustive books on a chosen subject. A single bad book can break them since the books are expensive (for PDF) and there are not that many of them. If I buy MMS:WE from XPR and it stinks then in 9 months when they have their next release - I am not likely to buy it. Each product is a matter of corporate survival (or at least corporate health).
I am a number two kinda guy myself (and you can take that in any way you want

) I do think that both styles will have similar profit margins in the long run - based solely on hunch here - the real question is what you want to do with your company? I am a one hit wonder. I only want to publish in the Last Dominion Line and that means style number one is right out the door for me since I would need 100 Mr. Smith clones to put out the volume that the RA or LPJ are doing (not to mention big boys dumping back stock into PDF as has been a trend here lately). I just cannot do the volume in 1 single line.
The big issue for style number 2 is having an impeccable reputation and getting that rep very well known. That takes time and effort, not just on ENworld but RPGnet, Gaming Report, and a ton of smaller sites like Silven Crossroads or Community 3E. It also means that you cannot afford to UNDERPRICE your product. You have to let people know before your first product hits the street that you have some good skills and can write a good product. How do you do that? Free stuff, website presence, writing articles for mags like Pyramid or Dragon, writing modules for Dungeon, and generally being around in the community.
I do not have VoFT but my guess is that you made a mistake by lowering the price. You just released it, it has been in the news, you are pimping it like a $2-hooker, and now you drop the price, what is a consumer gonna think? I would think that no one is buying it. Then I would wonder why and go somewhere else with my money.
