The market for $2 games on mobile platforms is already very wobbly. A few winners that make $$, but most dont sell much and quickly disappear off the radar. And spending $$ to market a 2$ game is a thorny problem with no answers.
In 2010-2011, I think many pubs and devs pinned their hopes on mobile gaming on phones, but it is not panning out.
The game industry is definitely struggling in the recession. Dedicated portable game consoles are floundering even in Japan. Home game consoles are turning into movie-streaming boxes.
PC games actually have a chance to regain some traction in all of this retail uneasiness.
