Favourite Visual Artist
Bill Watterson, I suppose. (Have you SEEN the artistry of Calvin and Hobbes?)
Favourite Movies
The original Star Wars trilogy, the Lord of the Rings trilogy, and the first two installments of the Godfather trilogy all come to mind immediately.
Favourite TV Shows
Avatar: The Last Airbender, My Little Pony: Friendship Is Magic, and Ed, Edd n Eddy are my favorite cartoons, while Breaking Bad, Game of Thrones, and Everybody Hates Chris are my favorite live-action shows.
Favourite Bands / Musical Artists
I tend not to define my musical tastes by artist; if a song catches my ear, then I'm a fan of that particular song. Now, that being said, Journey and Weird Al Yankovic are both musical acts that have produced a notably high volume of songs that I like.
Favourite Books
Watership Down, Tales from Watership Down, the Harry Potter series, and the Remnants series all come to mind immediately.
Favourite Writers
Richard Adams, J.K. Rowling, and K.A. Applegate all come to mind immediately. (This category seems a bit redundant in conjunction with the previous one.)
Favourite Games
The original StarCraft (including Brood War), the Mass Effect trilogy, the Halo trilogy (yes, that's the first three games only), Star Fox 64, Ocarina of Time, and Majora's Mask all come to mind immediately.
Favourite Gaming Platform
Of the past: N64. Of today: PC.
Tools of the Trade
Don't really have a trade, I'm sorry to say---unless making comments on others' talent counts, in which I use a keyboard.
Other Interests
I dabbled in fanfiction a few years ago, and may again at some point. I've recently gotten interested in muscle-training, though by no means competitively.
