"Premium" can be a somewhat ambiguous term when it comes to mobile applications. It could mean "exclusive" in some contexts, "expensive" in others or generally referring to higher quality. In the case of mobile game developers, it's probably supposed to be a mixture of all three. However, over the past year the idea of asking consumers to pay up front for a premium mobile game may be generating greater interest among developers for a number of reasons. First, there is the increasing scrutiny by regulators over how supposedly free-to-play mobile games are being monetized with in-app purchases. Then there are tactics from platform providers such as Google Play and Amazon, which have been partnering with select developers and publishers to distribute and market premium mobile games in specialty areas. Charging for installs may also be one of the easiest ways to track revenue. The question remains: How do you get people to pay? FierceDeveloper takes a look at the phenomenon in a new special report.
