I'd say that more than nine out of ten of the Kickstarters I back are at the PnP/PDF level. There's a very good chance that I will only make PnP pledges in 2017 as part of my goal to not buy any new games this year. PnP doesn't count :P
And there are plenty of good reasons I stick to the print and play level. Easy on the wallet and storage space. I like crafting games. And, frankly, I'm more confident on getting electronic files.
But sometimes, I lose track of them :D
Buttonshy turned out to be the one I was the worst offender on. You see, they offer black-and-white demo copies and we have a black-and-white printer. So I use those for the initial beater copies.
So I'll already have a copy of a game made but I forgot to get the final files :D
Anyway, I just went back and downloaded five or six files that I hadn't downloaded earlier. Often because I had already made the free version :D
