Liquid Marx

Liquid Marx is a serious VR game that bases its core game mechanics on the quantitative aspects of the economic theory of Karl Marx. The glasses with the liquids use a laboratory metaphor and represent the different quantities of that theory. 

The game mechanics are split into two main layers. On the strategic layer, the game is about maximizing one of those quantities over a certain period. On an operational layer, the game is about mixing and managing the glasses representing the different quantities.

Virtual Reality (VR) often brings itself the problem of cybersickness. On the positive side, it provides a far better spatial impression of the simulated scene. It allows for different interaction mechanics, usually evolving around the controllers and improved spatial perception. Liquid Marx minimizes cybersickness by putting the player more or less stationary into the center of a round table where all interaction relevant objects are placed on. The technical focus of this VR implementation is placed on the glass and fluid interaction. The fluid simulation is physically motivated but not accurate. On the one hand, this makes the simulation believable. On the other hand, it avoids usability problems like swapping or spilling of the fluid.  

The game has won a nomination on the Serious Games Showcase & Challenge competition.​
