I finished Wind Waker for the first time, specifically the HD version on the Wii U. It's definitely an improvement over the Gamecube one, but I think I'd still rank this as my least favorite 3D Zelda game. The swift sail was appreciated but sailing still sucks and serves no real purpose except to give the illusion of an open world and probably mask loading times. I was still enjoying the rest of the game for a while, though, and after the third or fourth dungeon I started thinking that maybe Wind Waker would climb up a few ranks on my list.
Then came the Triforce shards.
Good god, the Triforce shard quest is the worst thing to happen to Zelda since the CD-i. Nintendo did try to make it less tedious by cutting down the number of shards from 12 to 8 and replacing several charts in treasure chests with actual Triforce pieces, but even with those concessions it's still a boring, monotonous, completely unnecessary grind that would have been better off being dropped from the game completely and replaced with something else. Where previously I had been having a lot of fun, now I was just groaning and waiting for it to be over with. It's padding of the absolute worst kind that drags the game down for the sake of making it longer. At least the final boss fight was decent, even if the ending kind of sucked.
