From the introduction: I’ve grown tired of “killer dungeons in the old-school style.” For starters, there is no definitive “old school of gaming.” I was excited to see that term gaining use a few years ago and embraced it, but that was more because of the sense of community it encompassed than because the term itself had objective meaning. In almost every case, “Old School” means “back when I started playing RPGs.” If you started in 1975 with the original three little brown books, then that’s old-school. If you started in 2001 with edition 3.5, then that’s old-school. If you started in 1985 with Vampire: The Masquerade, then that’s old-school. Everyone wants to own “old school,” so as a defining term, it’s pretty useless.
