Eclipse Phase: Singularity
A specialization or field should be one to two words only and breadth/depth should depend on the skill used. Academics or Medicine is a pretty large topic with clearly defined limits, i.e. you learned this stuff in a class. If you have Academics: Politics then I have a clear idea of your body of knowledge since any topic you might apply this to has to be from a class or book. Interest and Profession are broader topics so they are definitely two-word fields. Interest: Politics tells me nothing about what the body of knowledge is and where you got it from; try Interest: Martian Politics, Interest: Political Crime, or Interest: Political Alliances instead. Same goes for specializations, so your Navigation (Planet) skill tells me nothing about where you got that knowledge. Try Navigation (Luna) instead if you’ve been all over the ol’ Dusty Grey or Navigation (Backcountry) if you want to generally be good at directing rovers anywhere from Mercury to Titan.
