In my opinion, james99 is right on the money. Spending more money on advertising is the most logical way to remedy the situation. As unfortunate as it may be, there is clearly a strong market for fart-based apps, and while that may not exactly be classy, who can say they have never in their life, laughed at a fart joke?
I think that a properly advertised (television, magazine, internet) iPhone application will sell well if it is truly a high-quality, full-featured video game. After all, who here wouldn't spend $20.00, $30.00, or even $40.00 on a full version of Mario Kart that would always be in your pocket? It's high time we saw the full potential of the iPhone as a gaming platform come to fruition.
Raising the App Store's Base Price to $4.99 Would Be a Good Thing
