Faust is my first attempt at creating a pygame framework for 2D game development. It includes most of what one would need to create a simple sprite based game with collisions, animations and UI.
MercLib is my latest attempt at the creation of a succinct game framework for XNA. Currently, everything required to create a free-standing local XNA game has been created and I am working to include more features as time progresses.
Castles and Catapults is a physical board game design I created as part of a game design class. It is a turn-based 2 player strategy game where players lay siege to each other's castles in an attempt to kill their opponent's king.
It is heavily inspired by games like Puerto Rico by Rio Grande Games and Siege by Mindscape.
