Chess
In the winter semester of 2013, I took a module at the Stuttgart University of Applied Sciences that taught us the basics of OpenGL. For this we had to work on a project in small groups during the semester. The assignment was to create a 3D scene with user interaction and lighting using OpenGL. So our group of three decided to implement a chess game (not necessarily creative, but doable). The original idea behind it, however, was a chess game with living humanoid pieces that get bored, for example, when they haven’t been used for a long time or hit another piece and fight it. After some research (so about 10 min :P) I found a game, which corresponded quite exactly to my ideas: Battle vs. Chess Its scope was way too much for one semester, but it was still a good inspiration.
