You may remember the founder of Ganesha Games who has commented on this blog some times. He runs a business making role playing games and such. And he just released an iPhone app with all the rule books and more. It's free. [Update: it's an iPad app and not all the books are free. Sorry for my imprecision.]
Update: Ganesha Games informs:
It's actually an iPad only app, not iphone. It won't work on iphones (well technically the app could work but the screen is too small to read)
You can use the app as a free pdf reader even if not interested in my rulebooks - you can import the PDFs from iTunes.
As a further clarification: the ebooks are NOT free, of course (well, some are, and there is a free preview of each book). If you know someone who has an iPad and plays tabletop wargames (battles with toy soldiers, fantasy or historicals) please recommend this app, they'll like it. Thanks!
"... the ebooks are NOT free, of course (well, some are, and there is a free preview of each book)."
That makes more sense. The way Eolake put it, I wondered what kind of way that was to run a business.
That's an interesting point. Yet, most of Google's services are free, and still it's one of the most successful companies on Earth. They sell ads of course, once they have the traffic. But you could sell other stuff too when you have the traffic.
Somebody said to me once: "you don't give away what you are trying to sell." But I have heard that some of the most successful authors of ebooks are giving away the first book for free, and earning lots of sales of their other books. (I'm sure it works best if it's a series.)
One of the earliest huge success stories of software, I think it was McAfee actually: they gave away the first version totally free, and only charged for further updates. This was astoundingly successful and paved the way for the Shareware concept.
People need a reason to come visiting, after all it is using their time. And people will not often talk about you and link to your site "just because you rock", but if you have some freebies they will, much more often.
Now, obviously if you give away everything for free, you won't make a dime. But if people have never tried a sample of your wares or don't have much of an idea of what you're selling, then you won't sell it either. I think the trick is finding the balance of what you give for free and what you charge for.
