Am I missing something?
Yes. It is extremely risky to do what appMobi does. If you want to make money you have to spend money 200 dollars is not a lot of money to start a business. The average cost to start a business about 10 - 15k. Most of the indie developers I know have spent that much on their business to get it up and going. Game salad used to be 2k a year and is now 5k a year. Plus 6 games 200 dollars i
AppMobi has to pay the bills and you can't do that by undercharging for the service. Unless you do not live in a first world country, 33 dollars an app is really not that much. People spend more money when they go to the bar.
Again if your goal is to make money you simply have to spend money to make money. If your goal is to make awesome games for everybody. You can get a website and upload your game there.
