Absolutely amazing game. Costly, but definitely worth it. The story is gripping, and brilliant. The gameplay is well thought out, well balanced, and a huge enjoyment. It is the most visually beautiful game I have ever played. I have often found myself just gawping at all the beautiful scenery in it, and have taken so many screenshots. The characters are charming and greatly developed.
I also applaud the developers for their incredible attention to detail. They brought in so much from the world of Harry Potter, that it really feels like you are living in that world. They used a lot from the films, but adapted it, modified it, and made it more consistent with the actual books.The inclusion of Peeves is very welcome, or the placing of the room of requirement actually opposite the tapestry of Barnabus the Barmy. It is a dream come true, to actually get to be a wizard or witch in this magical world.
It is a hugely enjoyable game, and you would absolutely do yourself a favour to get it. For me, it deserves 10/10.
Finally, I just want to say that I will never ever care about the reviews from sites that gave it a low score because they wanted to attack Rowling, and bully people who want to play the game, but clearly have never even played a single minute of it. Your job is to review games. If you can't do that, then find a different job. The harassment and even death threats that people who just wanted to play the game have faced has shown very clearly that online bullies who pretend to support inclusion and tolerance are actually the greatest hypocrites.
