apparently since i've left home BOTH my parents have begun playing, of all the games we have, the battlefield bad company 2 BETA. 
I laughed my ass off when 'lil bro sent the email saying so.
Hey, don't laugh, that's a great game.
its my very favourite game, but a pair of chartered accountants whos total previous experiences in gaming since the 80s is mario cart and the wii (mom) , and a
little XvT, CoD single player (dad), is quite amusing, in fact when my mom of all people engages me on a discussion about it when she came down to visit earlier today after my exam (pwned!) and is actually not talking like a total n00b, grasping concepts of cover and flanking, i can't not chuckle.
Now get them to play FreeSpace. 
THAT will be an epic challenge. maybe get the old man into Diaspora or FoTG.
OR if you ever release onto console / i get a linux build onto the ps3..
