I am 23 but I do find these Lego games entertaining. They are easy enough for kids to play but challenging enough for the adults to master it. It wasnt the hardest 1000/1000 but it was fun trying to earn it. I did give it a 9 for ithe level of entertainment for it's genre. Its not a mind blowing game or anything.
Good: Its LotR... whats not good about that? Legos still stick with mild humor in the cut scenes and make the characters personality stick to a "T." The achievements are labled accordingly too. With names like "thats still only counts as one" and "dont tell the elf," you dont have to guess what is required for them.
Bad: The only thing I can really think to put here is that if you are wanting to fast action Murder, Death, kill up in here, its not for you.
Ugly: I did find some of the balancing, swinging, and grabbing to be a little off. It may just be my expirence with the game though.
