User summary: Entalis, Reality Prime, is a science-fiction game core system and setting. The setting features numerous worlds that are accessible through a sort of hyper-space network of conduits. Characters are generated by selecting a Race (Human, Anarian, Omegan, Survivalist, or Kuldorian), a background and starting Occupation (roughly analogous to Class), and then generating Attributes randomly. Roughly half of the Attributes are rated on a scale of 1 through about 20; the other half are rated on a percentile scale. Characters then select Skills available to their Occupation and purchase equipment. The PDF version is downloadable as a series of files corresponding to the major HTML pages.
