The other thing that trips payware folks up is that the market DOES NOT CARE A WHIT what it cost you to create the product. If someone complains about the cost it will do you no good to talk about how many hours you put in, etc., etc.
You are entering a whole new world when you start charging for the product. You are no longer doing the community a favor. You are asking the community to shell out their hard earned dollars for what is effectively a luxury. Luxuries are the first thing to go when the economy goes south.
That is exactly my case. I have very few simming dollars to spend these days and while OFF3 may have cost these guys hours and hours of work I can't afford to care. I am on the fence right now with YAP2. I had to pass on SF2.
