Statistics
Typical tests with human participants often yield continuous data that depend on a group variable, for instance the time to reach a certain game level may depend on different choices of game mechanics. Such data are beset with strong randomness. How can one find the difference (if present) between the groups that may be buried in statistical noise?
Null Hypothesis, error probability, significance
ANOVA: Analysis of Variance
Kolmogorov-Smirnov test
Empirical distribution function
KS test against a given distribution function, table
KS test for normality
Integrate a game story with reality. Find not entirely unplausible reinterpretations of actual events, places, and persons. (This is related to esoteric/magical thinking and to conspiracy theories.) Digital media are merely used to create or support the illusion, such as Web sites of fake agencies.
Advantage: high realism and immersion; no expensive 3D production; easily accessible to spectators and casual users
Use: advertising (viral marketing)?
