Aside from the projects you can see, Tetraspace 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.
Concretely, for instance, delicate game balance is critical in regards with the concept of flow. (A game that's too easy is boring, a game that's way too hard is demoralizing.) Every player has different skill levels, but not only that, each also has different skill levels in each facet of gameplay. (In an adventure game, a player can be good at combat but poor at puzzles, or conversely.) How is it possible to design a game balance that ensures it never gets boring or demoralizing for any given player (in a target audience)? Difficulty levels or adaptative difficulty is a good start, but the actual answer is way more subtle than that.
Now, what about the UX, how menus are organized, possible "quality of life" improvements, accessibility, etc. They are all important and we'll pay attention to those as well.
