I made an iOS/android/kindle game that I spent about 4 or 5 months on. I think I've gotten about 8 downloads. My problem is I'm a marketing doofus and really failed to get the word out. But yeah, definitely a depressed potato.
I wouldn't call my game a diamond. More like a thing I want people to play and see. Also some money to pay for food would be cool.
if it is your first game, make it free to maximize exposure, if it is good enough to keep players interested you have a great place to market your future games.
I agree with Simon.
Personally, I prefer it when people have a donate page on their game site rather than ads popping up all the time. People with money will be generous if they like what you've made. So what if 1000 people play your game and only 1 persons gives you money for it. What if that one person gives you 10,000 dollars? Stranger things have happened.
