I've played my share of harry potter games on the PSP but this is one of the harry potter games that has bad graphics...

User Rating: 4.5 | Harry Potter and the Half-Blood Prince PSP
Graphics: 2/10
The graphics of the game gets worse and worse especially when your playing a Quiditch Match (cause the players in the Quiditch looks like flying paper dolls).

Sound: 3/10
Good: it's good when you cast spells and making potions.
Bad: no voice acting.

Gameplay: 6/10
Not bad when your playing minigames and making potions.....but this game could be better in [many] ways.

Replay: 8/10
This is the best thing about the game! Once your done there's still more to do like collect ingredients for you to make potions,play minigames and earn trophies, collect famous quiditch players and many more!!!!

Overall: 5/10
It's not the best harry potter game but it's sure gonna keep you playing until you fall off.Though it's very dissapointing that they couldn't make the feeling of the movie into the game.
