I'm mostly a Marvelite, although for many years now, I've given up trying to keep pace with what goes on in the MU. It's all too much, but I try to catch up when I can, thanks to Marvel Unlimited.
My favorites are primarily from the mid- to late-70s era of Marvel's monsters (Man-Thing, Tomb of Dracula, Werewolf by Night, and so on). Also, was a fan of the X-Men through the late 90s (mainly, Nightcrawler, Shadowcat, Rogue, Storm, Colossus and Wolverine).
Other favorites: Star Wars, Concrete, Hellboy, Cerebus.
Other geek interests: movies, TV, James Bond, SF, model figure kit building, trading cards, X-Files, music (on MP3, vinyl and CD)
