My least favorite so far is Twilight Princess. I care about the full package (story (don't find It very important on Zelda though), graphics, exploration, sidequests, songs, dungeons, use of items, etc) and I highly believe that Twilight Princess failed at that. It's a good game, but not a good Zelda game. We had a terrible job done with quite a few items where their uses was pretty much limited to very obvious things on a dungeon or two, puzzles were generally easy, songs not that memorable, unecessarily big world which contributed to make It feel empty and there is probably more I'm missing or not feeling like saying. I really think I could write a bible long review about how much I hated TP, but I guess I'll save that that for later.
