I sometimes get the feeling that this is the only game HN plays. When people talk about not being able to switch away from Windows due to games, it seems like someone always responds, "Well Kerbal Space Program runs on Linux and that's all I care about." I don't think I've ever seen articles similar to this one about other games gain as much traction. Can't think of very many articles about games getting to the top of HN at all, actually, unless they're about John Carmack writing one.
