I suppose if you're counting free-to-play games, most other days did have something free, but I personally don't consider downloading some MMO-esque game I never had any intention of playing,and then playing it just long enough to get a random achievement, to be "free" in the sense of actual effort required. I'd much rather buy a daily deal game that I'd previously been interested in.
Wheee, up to 15 coal now! I do want to save some for the prize drawing, but I may go ahead and craft 7 just for the hell of it, since there's not much functional difference between 8-in-several-million and 15-in-several-million odds. I can't really complain, since I did wind up with a great game for free near the start.
