From other questions about intellectual property, it's my understanding that:
- "measurements of observable fact in the world ... are not copyrightable", but arrangements of the data are.
- fictional languages are not copyrightable, but works using them are.
- unique names can be trademarked, but not generic ones.
What about measurements of fictional worlds? Many games contain tabular data that describe how elements of the game interact with the rules. Does it matter if the quantities being measured have real-world units or not? For example, 1st edition AD&D has tables of weapon properties, such as length, weight, price, speed factor, damage dice, and armor class adjustments.
Assuming that I design my own arrangement and appearance, is fictional data covered by copyright (regardless of fair use)?
