At the very beginning of my university career in game design, I wanted to start making games with my 2 friends. One of those games was called Office Wars in which you are a worker in a cubicle and you need to wage war on your cube-mates. I had worked on creating 3D objects that were to be used in the game.
Keep in mind that this was completely self taught! I used Cinema 4D to create these objects. Sadly, this game never came to be.
