So you rented the game because you liked the books or have seen the movies, cool... you're in for a ride.
Don't ever play this game on hard (for the achievement), you will have nothing but frustration ahead of you. Unless you are an international champion at chess, you will have an incredibly difficult time with Wizard's Chess and an even more frustrating time as the Gobstones AI perfectly knocks their gobstones out while just barely staying in. This game was intended for children and adults, but completely unbeatable for the average player looking for achievements.
Playing on Hard, like the achievement warrants so many to do will also make class minigames downright stupid. There is no timer and therefore, you must work on pure speed and after all of that, you will have no idea whether or not you've completed your goals on time until after the game has flipped you the bird for what could be construed as a millisecond off.
It's great and all, seeing the castle, but it seems like all you do in this game is show off magic for useless purposes, there's actually an achievement for cleaning up the castle. Yes, Harry Potter: Caretaker is obviously in the works.
While the voice acting is fairly regular, after hearing every single line be spoken by the AI and some of it unskippable (especially after listening to the Gobstones play going "Ha ha!"), you'll be incredibly tired and the reused "Hedwig's Theme" will play on your nerves after an incredibly long and useless intro sequence every time you load your game.
Furthermore, casting with the right stick also wears on the player, they couldn't have possibly forgotten that there are four other buttons on the face alone and targeting seems to be on a whim, it will briefly shimmer the target as if light was reflecting off of it, but you have little idea what you're really aiming at.
If you really are a diehard fan of this game, don't play for the achievements. You will only find frustration here.
this gamed was horrible. it was no fun at all. It was also way to easy. another thing i didn't like was how in some places in the game it zooms out really far and you cant see where you are going. It also doesn't follow the story very well. the one good thing was when you are looking for somebody you can go to the marauders map(magical map)and click on the person you are going to find and it guides you with foot steps on the floor. I wouldn't recommended it.
