Positech does not use DRM for any of their games. In fact, the developer performed a poll, asking people to tell him what their reasons for pirating his games were. What he got back is fairly interesting, and the result is here. That also made him go back on his plans to start DRMifying his games. Some of them seem interesting as well, and one of these days I will have to buy a few of them I reckon. I suggest those who are as sick of DRM as I am, go check the games out.
