Game a week challenge
Of course the best way to announce something like this is to actually make a game. Allow me to introduce imPede.
imPede is a 2-player abstract played on a pentagon grid. Each player must make 4 moves each turn and tries to outmaneuver the other and put them in a position in which they can't make a legal move. Fairly simple really but a good start for the challenge. Enjoy :0)
