There is a game that I came across a few days ago in which you could expand your vocabulary and help in an effort to end world hunger.  This free game is called ‘FreeRice’, and the goal is to find the meaning of a word that is displayed on the screen, and for every question you answer correctly, you will have donated 10 grains of rice to the effort.  I play the game from time to time, probably donated a total of 10,000 or so grains as of yesterday.  Give it a try, you will be helping in a bigger cause just by playing the game.   I think that this game is a really interesting take on what a game could and can be, which is mainly why I posted this on here: to give an idea of what could be capable.
