> provide marketing campaigns that help publishers get their games in front of users.<p>It would be more accurate to say those campaigns help get their games in front of <i>other games</i> in front of users. Advertising is an arm race, a consumer is looking for a game to play, the only question is which game will catch their eye first. But if you phrase it this way, it becomes obvious advertising and app stores (that function mostly as advertising in this case) don't provide nearly as much value as they claim, and are mostly parasites.
