Of course it's quite funny times to revive childhood memories by "re-enacted" film stories. The game is not too badly done: The abilities of the characters are very diverse and the levels, designed with attention to detail. However obscured not the weaknesses of LEGO Harry Potter. The levels are too long and basically too easy. You never actually stands in front of the problem that you can not know what you should do now. Partly this is even quite well, because outside of the levels you have much more freedom of movement than with LEGO Star Wars (just the Cantina). But the levels are rarely correct puzzles, everything seemed very out.
I am a young man, but also more of a friend from the Star Wars Action with spaceships, laser swords, correct slaughter and so on. In LEGO Harry Potter trying all proportioning sets rather failed. Sure, you can destroy objects with numerous spells. But the reference to the films can not be excluded a halt, and not just get wild and action-packed.
I've bought both parts, but after the year 2 lost motivation from the first part to continue playing. There is nothing like LEGO Star Wars. Who Harry Potter but rather like the like those games one probably already rather. My sister likes them.
