i too like history. more US Civil War and WWII, though. i am also a complete comic book nut. comics are in competion for my most wallet sucking hobby with Macross. titles i read include:
Alias, Fables, Losers, Y the last man, Global Frequency, the Legion, Powers, Stormwatch Team Achilles, Wildcats 3.0, Sleeper, Batman (Jim Lee's Hush run), Sojourn, Queen and Country, New X-men, Outsiders, and am trying to finish out my old Gen 13 collection (first series). i highly recomend these titles to any comic readers out there!
i try and keep up on current events, so i could say the news is my hobby as well.
Lately, i have been reading a lot of Stephen King books, mainly the books connected with the Dark Tower series.
