===== style ===== On the surface, HG looks like a pulp space adventure. However, that doesn't define it. In fact, it shouldn't be describable by any sole genre: it aims to blend comedy, drama, adventure, surrealism, horror, mystery, etc. It is thus quite hard to tell what fits the style and what doesn't. realism ======= In terms of laws of nature, some realism should be kept; unnatural things or behaviour should be explainable (unless there is specific reason to do otherwise); but other than that characters and societies have full freedom to be weird. adventure ========= Used as a main source of plot advancement. humor ===== * subtle is better than bold, though latter has its place too * parodies are fine as long as they are not dominant * forth wall shouldn't be actually broken, though occasional subtle hints on it are fine drama ===== Drama is always welcome, both as means for additional humor effect and actual serious drama. moral choices and ambiguity =========================== Moral choices should be common, sometimes without any 'good' option (or, perhaps, with one leading to dead end).
