I too learned how the guage of a shotgun is derived. But not because of gaming. Just because I was thinking about guns one summer. And so, naturally, I wanted to know why a 12-guage is bigger than a 20-guage.
Its a reall archaic and pretty bad measurement system, imho.
White Wolf helped with the SAT. And that was nice.
However, when it got time to take the GRE, gaming coudn't help. I think the GRE board just makes up those words. Afterall, if White Wolf doesn't use a pretty obscure word, then its not really a word, is it?
