Animal Crossing debuted as a weird, unique, and very Nintendo-like video game in 2001. It resembled popular life- and farm-sim games, where your experience in a small, riverside village revolved around simple tasks and monotony. But Nintendo added a very special pinch of time and patience.

There simply wasn’t much to do in a given day after fishing, fossil scavenging, and running basic errands. That was the point. You were supposed to hop in, do your daily virtual regimen, leave notes for other players in the same household, and come back in a day or two. That formula has since shone for over a decade, with follow-up entries adding online support that essentially expands that “cozy little household” feeling without breaking the game’s core loop.

That’s why fans were understandably excited about the series getting its first smartphone entry, Animal Crossing: Pocket Camp, which is now out on Android and iOS. The series’ mix of simple, bright graphics, cute animal friends, house decorations, and quick-hit daily tasks seems like perfect tap-and-go gaming fodder. And many of the series’ best and weirdest trappings are in this smartphone version. But before addressing any of that, we have to look closely at how Nintendo converted this game from a fixed-price, retail offering to a free-to-play microtransaction disaster—and how that has rotted Animal Crossing‘s most rewarding elements from the inside-out.
