No worries. As this is for a good cause, I can also collect the lappy from you, fine tune it ( XP, virtual CD & Games ) and have it delivered to you in a couple of days, should you wish for this ( at no cost ). I do this quite often with asylum seeker & refugee communities in Switzerland and sometimes abroad.
Some games you might want to download yourself first include:
World Food Program http://www.food-force.com/index.php/game/downloads/
Open Source Windows Games http://osswin.sourceforge.net/games.html
and many more
