I genuinely hate how apple has pushed microtransactions as the only viable route for app/game demos on their platform. I want to try out an app or game for free, and then decide if I want to purchase the full thing or not. This is how games always worked, and this is how Steam / PS3 / Xbox work.
The infrastructure apple provides however forces demos to live in the same category as microtransaction games, and as a result, the best games either get lost in the sea of free stuff, or completely forgo a demo and just list in the paid section. Quality content doesn't stand a chance.
