I second @BrianRubin's excremental exclamation! I DID buy in this month expecting (as has happened to me in the past) to basically just get the preview game, Dragon's Dogma, for a good price and be disappointed in the rest. NO SIR! Mordheim is a fantastic bonus, and then Flame in the Flood on top of that is amazing. I don't own Escapists either and have heard good things, so I am very pleased this month! $12.00 well spent.
Warhammer : End Times - Vermintide is the preview game for next month. Yet another game I am interested in at a price I am willing to pay...though I may hold off to see what it goes for in the upcoming Xmas sales before pulling the Humble Monthly trigger.
