While I enjoy programming and game development the most, I have many hobbies as well. Some of these tie into my game development endeavours in some way, whereas others are purely for fun.
I am an avid musician. I grew up playing piano, played drums in the school band, and am now obsessed with guitar. I also write my own music; I will definitely post some here someday, when I have something more polished. At the moment though, my priorities lie elsewhere.
If I'm not making games, I am something of a gamer myself. I enjoy a variety of games: some with slow-paced and relaxing progression, some that make you have to think hard about every move, and some for hectic fun with friends. I think that as a game developer it's important to play games yourself, because you can get inspiration from your favourite things in every game you play, and use that inspiration to enhance your own projects.
I'm also fond of non-electronic games, such as the iconic Dungeons and Dragons. I suppose that in order to be a programmer, one needs to meet a certain quota of nerdy hobbies.
