My favorite thing about the Zelda games is they take so darn long to finish.  In this way, playing a good video game is like reading a good book.  It takes a long time, but it's worth it.  This game tells a great story, and it really immerses you into another universe.  You're placed in a different world with different limits, and it's like you live a whole other life in a few months (or days, if you're a hardcore gamer).  You follow Link through trials and tribulations on the quest of a lifetime, and fighting them ugly video game monsters is a nice way to have a bit of fun after a long day.
