Twilight Princess is my favourite, its dark like MM but has more of a story rather than sidequests (though MM is more darker and is my 2nd favourite)
OoT is pretty fun wee game, i like to casually play that because it isnt so hard or anything.
and the rest i havent played much tbh, but AlTTP is good but haaaaaaard as hell, well except the 1st 2 are harder than hell (but thats just me)
and Links awakeing is tough but just a fun wee land to run through
