I'm a sucker for both incredibly destructive hardware and incredibly cute things in my entertainment.
In high school, I once allowed myself to briefly let my hair get set on fire out of sheer boredom. In the middle of class.
I find that some wargames (especially MJ12's) to be less limiting to my self-expression than most tabletop RPGs, for reasons I can't quite fully articulate.
I love history, but can't stand it when other people nitpick a historical movie/whatever to pieces.
I've read two of China's "Four Literary Treasures": Romance of the Three Kingdoms, and Outlaws of the Marsh. In translation, though.
