This has probably been done before but I'd like to see a needy module that is well, chess! I would imagine it starting with a random chess layout of pieces of both sides, starting more towards the end of your typical chess game. Make it so that you must make a move before a set time or the chess ai opponent will take a turn. It would be a mix of surviving against the ai opponent, if you at any point lose your king the bomb explodes. An additional idea I like is that you may optionally make moves at any time, if you win the game the needy module would disappear or alternately make you lose a strike. After you make any move the ai always takes a move if that was not clear. It only takes the additional extra move if you don't make yours in time.
