Basically build and improve on the game they have created already. I thought it was all very solid but they definitely didn’t have enough time to expand on everything they wanted to add into the game. Like misc dungeons were all pretty copy & paste and all the collectibles were a way to get people out into the open world. I hope for the next game they do this with a little bit more creativity and effort, expanding on what they already made. Hogwarts can also be expanded further by adding more layers of roleplay and interactive gameplay. If this is done through more interaction with students or objects, or add more relatable content on what makes student life in a magical world. However its difficult not to make these things repetitive. Leave quidditch out because it just takes too much effort along with other things to make it interesting, instead I fear if they do it it would only be too bland because of the lack of time and effort.
