My latest post on TechCrunch asks whether mobile gaming has reached a point where it is no longer a simple business. With the layoffs at Zynga and Tapjoy, are looking at some canaries in the coalmine? Are we at the point where even the plugin business (monetisation tools, sharing etc) have too many competitors and are about to have a cleanout? Are we entering a phase where relationships and partnerships with platform holders will matter most? Most importantly, will the audience for mobile games follow a line where it becomes more sophisticated and interested in deeper content, or will it remain strictly lightweight and novelty-driven?
