Since, I've just started playing this yesterday, I can't really give the full spec reviews but of course you guys can google it yourself right?
But I'm highly recommending this game because:
1) One ring to rule them all
2) Don't let your 3ds get wasted with some crappy games
3) Lego orcs are cute
4) Easy gaming navigation, instructions appear as you play (because I'm too lazy to memorize everything)
5) A cartoon and cuter version of the trilogy
6) Backgroud musics are epic!
7) If you're playing as a character, you can beat others to death and they'll be alive again
8) Lego Saruman is cute
9) Lego Nazguls are adorable
