We don’t normally post about Humble Bundles but Positech are really great and the founder (Cliffski) is a developer well worth supporting. You can pay what you want for the bundle and get Gratuitous Space Battles, Gratuitous Tank Battles and Kudos 2, if you pay over the average you get the excellent Democracy 2 as well. They’re all unique games with a distinctive element of strategy and choice. This is a weekly sale so don’t dither, just go for it!
