Liquid Marx

Karl Marx, his theory and its social consequences are a highly political and emotional subject matter. Game mechanics in contrast over stories have the characteristic of de emotionalizing subject matters. Liquid Marx is a serious VR game whose core game mechanic is constructed upon the quantitative economic theory of Karl Marx and uses glasses with liquids as metaphors for the different quantities.

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 of time. 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 cyber sickness. On the positive side it provides a far better spatial impression of the simulated scene and allows for different interaction mechanics usually evolving around the controllers and the improved spatial impression. Liquid Marx minimizes cyber sickness 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 one hand this makes the simulation believable. On the other hand it avoids usability problems like swapping or spilling  of the fluid.    

Beta version 2 released

The beta version of the game can be downloaded from the download page. The version 2 (updated as of 05/28/19) contains all the experience that has been included from the playtest in the Karl-Marx-Haus (see here)

Report in local newspaper

The largest and most important newspaper for the region around Trier "Trierischer Volksfreund" has written a report about the project. It can be found here (in german).

The core game takes place at the table on the left side and the room contains further exhibits.
The picture displays the pouring of liquid as one of the core game mechanics.
