Legend of Zelda - 8 (amazing classic, great music, sense of adventure, freedom)
Adventure of Link - 6.5 (solid game with some great things, yet some flaws)
A Link to the Past - 10 (near perfect 2D action adventure game, great music, memorable characters, tons to explore)
Ocarina of Time - 10 (a truly remarkable achievement, an epic tale with great pacing, incredibly memorable characters, great music, and an eerie sense of mystery)
Majora's Mask - 9.5 (one of the most unique game concepts ever, an amazing foreboding and creepy atmosphere, best NPC side quests in the series, great music, some slight flaws regarding ease of boss fights and non ideal save mechanics and some recycling from OOT)
The Wind Waker - 8 (a great sense of adventure and simply oozes charm, beautiful game, too easy, too short)
Twilight Princess - 7 (a solid game with several flaws regarding pacing, difficulty, and sidequests. some of the best dungeons in the series, yet they exist in isolation with little integration between each other and the overworld. meaningless side quests, not enough character development, too much recycling from previous entries)
Phantom Hourglass - 3 (some neat concepts for weapon usage and controls. DS hurts the beautiful windwaker style, very little incentive to explore, too easy, generic music and atmosphere)
Spirit Tracks - 5 (definitely some of the more creative puzzles the series has seen in a while, a lot of unique mechanics, a lot of integrated and creative item usage. the overworld is a disaster: the train is too slow and never gets upgraded, it is tedious, no exploration, overworld music ok, not enough to compensate. a slow tedious transport method was a terrible decision for a portable game. literrally on a train waiting for my train on the game to arrive to its destination, very tedious and meaningless side quests.)
