Wizards Unite is off to a slow start compared to Niantic's gargantuan Pokemon Go. Inns serve the same function as Pokestops, while Portkeys are similar to Eggs; after you've used either a Gold or Silver Key (Wizard Unite's version of Incubators), you'll need to log a certain number of steps and the Portkey will take you to a Wizarding World location.
Even so, the new game doesn't quite match the breakout early performance of Pokemon Go, which quickly became a worldwide phenomenon when it was first released in 2016. According to new data from Sensor Tower, the new Harry Potter title has now notched 400,000 installs and counting, with players spending more than $300,000 across the iOS and Android app stores.
The name game is also ranked at the time of this writing at No. 102 overall for U.S. iPhone spending, according to Sensor Tower.
The game's predecessor - 2016's Pokémon Go - managed to generate $2 million from player spending in its first day in the wild, having only been released in the USA at the time.
Overall, the game seems to be a good bit more complicated than "Pokemon Go," with more complex combat mechanics and more achievements to pursue, though there is obviously a lack of collectibles in the form of the dozens upon dozens of Pokemon creatures that can be captured and trained.
