Just as GURPS Infinite Worlds ties together all of the GURPS Settings, the celestials of this game tie together time and space. By playing celestials, the players can be transported to any era in history or fiction. The celestials are too extraordinary to be called “realistic”, but they move between eras populated by realistic humans. GURPS In Nomine is a Third Edition book. From the Third Edition Basic Set: “In a cinematic campaign, PCs should start at 200 points, rather than just 100. To maintain some touch with reality, PCs may not spend more than 150 points on their basic attributes; the rest must go into skills and advantages.” This reflects the Third Edition’s “default” of 100-point characters. The Primal Gods game will start with 500 point celestials; decidedly cinematic according to the Third Edition Basic Set. However each day of celestial time is at first billions of years of our time, so celestials may travel to our universe on their sixth day and spawn a GURPS Ice Age game, or come on the seventh day of celestial time and spawn a Star Wars game, etc. In each of these spawned games, the characters will be mundanes, so the resulting games will start out as mostly realistic.
However, in the Third Edition’s Compendium II, it says that “cinematic” is a style not a point level. Nevertheless, all the games will be mixtures of cinematic and realistic styles, subject to the judgement of what shall be allowed by the game-master. This holds for all of the Fourth Edition material and rules that are used as well.
