Although Harry Potter: Wizards Unite is being developed by Pokemon Go developer Niantic, there are still multiple lessons it can stand to learn from Niantic's flagship catch 'em all game. Here they are, from three die-hard Pokemon Go players on the IGN staff.
Make Our Collection Useful
While Harry Potter: Wizards Unite shares a lot of the same mechanics as Pokemon Go in terms of its basic mechanics (catching Pokemon on the world map vs. catching Foundables, for example), the thing that differentiates Pokemon Go is that the Pokemon you're collecting can be used for things beyond simply adding to your hoard.
Depending on what Pokemon spawns, its IV ratings, and level, it could be utilized right away in other aspects of the game. In Wizards Unite, you're basically just scrapbooking and adding stickers to your notebook — which is cool the first few times, but feels worthless and grindy the more you come across the same Foundable. By contrast, in Pokemon Go, I could catch 10 Charmanders in a row, but every single one of those will be different in its level, moveset, usability, etc depending on what I need at a given moment. Maybe I will evolve that Charmander to a Charizard to use in a raid or PVP battle, or maybe I caught an ultra-rare shiny Pokemon that is just nice as a high-value collector's item.
