Not much to it...
I got the urge to buy it one day. I can't say much about it. The graphics and sound were OK.
The gameplay was ARIGHT. You can't use much spells except for accio, jinx and maybe one or two more. You fight along side Ron and Hermione (or you can be one of them). The levels system is very confusing because you need to collect a certain amount of Triwizard shields to compete in the Triwizard asks, but there can be more than one shield in a level, so it gets boring going back in the same level, especially when you find no more shields or you can't find it at all. There are some Moody Chanllenges (ex. y have to cast certain spells to jinx dungbugs or whatever they are called a certain way). The second Triwizard task level is basically pointless, you just collect jellybeans (you do this throughout the whole game) and swim in a circle...boring! I didn't play the game that much, but my sister did and I helped her with the last triwizard task and the last level (defeating Voldermort) which were two very easy levels (I used the walkthrough). Some levels had a puzzle theme (for ex. to collect one sheild you had to go get a giant boulder and walk up this plant root...my sister figured it out because I got too bored and frustrated with it. You can also use cards to equip each player with: they give them extra power, strength, stamina, ect...nothing much. Over all the game is OK, but I would rent it first if I were you.
