Too short story mode. I completed the story mode in less than 4 hours.

User Rating: 7 | Harry Potter and the Half-Blood Prince PS2
Graphics- 8.0
Graphics is the best part of this game. Hogwarts looks real with new places.
Potions looks real when you are making and when you are playing quidditch the envoirement looks very very good. Harry and others look different from the previous game but do not look better in anyway. Now i want to tell you something if you want a great look of Hogwarts go to Owlery stairs (not inside)
and you can see Quidditch ground, Hogwarts, Hills and rivers with a great look of forbidden forest(Forbidden forest looks better when playing quidditch, but not other places). If you are a die hard fan like me then you enjoy it for 5 minutes. Cut scenes are not good in this game.

Sound- 7.9
Voice acting is not good in this game. But envoirment, spells sounds very good. When poeple talking around sunds also good. When you are playing quidditch Dean's commentry makes you entertain but it is very slow.

Gameplay- 7.3
This game could be very good if its hard it is too easy as you can win duels from death eaters very easily as a 1st year student. Potion making is very good in this game but quidditch is not so good because you just have to use your L stick to fly through stars if you miss stars you could be defeated. There are only 8spells(Wingardium leviosa, depulso, incendio and 5 duelling spells) in this game. You have to find 125 crests and 25 mini crest. You can join three clubs potions club(where you can make for mission, side missions and optional missions), duelling clubs for all four houses and flying where you can play matches and tryouts. You can win some badges if complete any specified objective. There is no room of rewards in this game so no videos, awards or unlocables like in previous game. There's no map you just have to call Headless Nick who takes you where you want to go. This game is totally different(nearly 99%) from the Order of the Phoenix.
The game statrs with a cut scene where Snape makes the unbreakable vow and attack by wizards on muggle world. After the cut scene you are in the Weaseley's house where you talk to Ginny and Ron and fly to catch the snitch and then to Hermoine and Ron where you learn depulso spell.
You can't even discover Hogwarts. You just can duel, make potions and play quidditch and collect crests. You can't do anything else than these four things.
It is not better than the Order of the phoenix game.
