As a typical computing science geek I tend to play a hell of a lot of computer games. My favourites tend to be strategy or FPS games. At the moment that means Dawn of War (looking forward to the sequel) and Company of Heroes. I have a Wii and a 360 and play them frequently although I tend to finish with games on them quicker. Wii sports and Mario Kart Wii are the current replayable console favourites. Old time favourites include Civilization, XCOM (Ufo:Enemy Unknown) and the half life series.
I'm a particular fan of films along the lines of the Princess Bride, Ghostbusters, Airplane, Hot Shots, Spaceballs and The Naked Gun. I also like a fair number of the "good" war films; Das Boot springs to mind here. TV would include QI, Red Dwarf, Firefly, Stargate, Battlestar Galactica, Family Guy, Futurama, The Simpsons, Scrubs, Father Ted, Police Squad, The IT Crowd and Top Gear. Books will be Douglas Adams, Orson Scott Card, Isaac Asimov, Robert A. Heinlein, Arthur C. Clarke and more recently Iain M. Banks.
I have quite recently taken up Fencing; (as in sword not as in garden). Mostly Epee although I occasionally do a little bit of Foil. I'm improving.
