Malleus monstrorum
I really don't like using a laptop to run tabletop games. Its kind of a line I draw in the sand. Even if I wasn't in prison, I really don't want to have to consult a PDF on a fuckin computer for information while I'm running a table. Tabletop games are supposed to be a way to game without electronics. Its the gaming equivalent of going camping. We can still prove for now that we are better than a computer, until they invent some kind of neural jack that plugs into your spine so you can bang octopuses in nun outfits on the moon or whatever. And so I really need a goddam paper copy of any book I'm going to use.
Maybe I could consult the PDF before the game and print out the part I need, but that won't work if for example, the rulebook was a PDF. What happened to chaosium ? Why can't they print books anymore ? Is it some gay environment shit or something ? Just make the books out of recycled diapers.
