This is the cheapest this has been since the holidays. My soon-to-be 6 year old just finished this game. Just wanted to share that I thought this game was a bit harder that say Lego Star Wars or Lego Indiana Jones. Those two games are more straightforward and with Harry Potter you need to learn spells and learn when to use them. the game is a lot of fun but I don’t think I would say this is for younger than 5 years old.
