When I made that pledge, I gave myself some loopholes. Thrifted games don't count but within reason. Games for the toddler don't count BUT I can't say 'Sure, he'll play Terra Mystica'. I initially said Kickstarter didn't count but I set a small and strict budget. Since then, I changed that to only getting PDF files for PnP from Kickstarter, while still sticking to that budget.
And, of course, print and play doesn't count and is fair game.
So, how have I done so far?
Lets see, I have made a lot of PnP games (a good chunk for my solitaire binder), I've stuck to my Kickstarter budget and only buying PDFs, the doodle has gotten some games and I've gotten thrift copies of Rolling America and Qwixx. And those only squeaked in by being a dollar or so, taking up minimal storage space and being games quick and easy to get on the table.
So, yeah, I'm doing pretty good.
