I'd go as far to say, that if we can't have a PDF of the rules, we probably won't play it.
This is becoming more and more important to me as well. I rarely have time to read game rules except before bed which means I get 5 pages tops before I pass out and I have to read by tablet so I need the PDF...heck I even shelled out $6 for the Battles from the Age of Reason rulebook despite PAYING ONCE to buy the damn thing with the game because it's worth me having. I find that approach 100% repulsive, but apparently even 100% isn't enough to keep me from shelling out my $6.
