Whenever I see a page selling anything and it won't tell me the price and I can't find it in a click, I move on. My time is valuable, and someone who plays games to waste it is not someone from whom I want to buy anything.
Additionally, this is not about playing games -- it's about finding what is valuable to a client and delivering it.
If SIAI approaches me to buy $WIDGET and Google approaches me to buy the same $WIDGET, I'm charging Google an order of magnitude more than I'm charging you.
