Aside from making guides, Tetraspace also offers ludology consulting services for designers.
Ludology is the scientific study of "play" (enthusiastically engaging in a ludic activity). Ludology is a rather broad interdisciplinary field that involves numerous cognitive sciences like psychology and sociology. It also involves concretely analyzing gameplay systems using calculus, information theory, statistics and operations research.
We focus more on the applied branch. We like to objectively analyze gameplay systems on all possible angles.
