Me, my gf, and her two sisters have been having a great time with this one. I think the best part is that if one person can't show up, another one can take their place without having to worry too much about what's going on or what stats they have or weapons etc. FF:CC had that problem as you'd be playing someone elses character if you took over for them and that doesn't work too well as a lot of the stuff you can customize, it's all on an individual basis rather then following some set path of leveling up. Makes Zelda much more multiplayer friendly especially since all your hardware resets at the beginning of the next level.
Aside from that, it really is a great game. The best parts are definitely the puzzles and the neat ways to get through them. The dark world dungeons (level 2 as mentioned) in particular are very well done. World 4 at this point is pretty underwhelming. Really not multiplayer friendly and the puzzles aren't all that imaginitive, but who knows. Plenty of game left to make up for this portion of it.
