Hi there guys I need your suggestions. Do you know any system or game that is not that hard to program, like something that can be done for less than 3 weeks because I need it for my term project. thank you for those who will help out.

You could do something like the dice game mentioned in this posting.

One part of the team could work on the dice engine, another could work on the game engine and another could work on the user interface.

It could be done as a graphical representation, web app or from the command-line.
