Zelda Director Eiji Aonuma feels he did not make Twilight Princess as epic and grand a game as he intended. He said that he regrets making Hyrule a realistic, grand size, saying that with that size, they were unable to fully take advantage of the space that they created. He has said he plans to use that grand scale as a starting point in the development of Skyward Sword.
Fan Nickname: So, this Link is the "Hero of Twilight/the Gods/Light," right? He must be, because three of the numerous other Links throughout the series had similar titlesnote He's referred to as the "Blue-Eyed Beast" in-game, but that hasn't really caught on because it's specific to his wolf form.
I Knew It: It was heavily suspected by most fans that the Hero's Shade is actually the Hero of Time, due to strong yet cryptic in-game hints and the series manualHyrule Historia eventually confirmed that. The other theory that TP Link is his descendant was also confirmed.
Technology Marches On: Part of the reason for the eventual backlash against the game's graphics (see Hype Backlash). When this game first came out, the fact that it had a detailed, realistic art style, instead of being cel-shaded like Wind Waker, was celebrated and considered a return to form for the franchise, and seemed very advanced to gamers accustomed to the sixth generation. The problem was that detailed and somewhat monochromatic graphics proved quite popular on the Xbox 360 and PlayStation 3, which could do them much better than the Wii and GameCube could. As a result, Twilight Princess began to look very dated very quickly, while the cel-shaded graphics of Wind Waker (even without taking the HD remake into consideration) have aged considerably better.
There was also originally going to be a magic meter, as can be seen on the Wii version's boxart. It would presumably have been used for the Hidden Skills and transforming back and forth.
The companion game, Link's Crossbow Training, was meant to be a direct sequel akin to Majora's Mask. However, production would have taken too long so it was decided to be a simple spin-off to take advantage of the Wii Zapper.
