We have a Wii, and my husband had fun with my son playing Super Mario Galaxy. The main player, in your case a teenager, can play the game, and a second player, who could be of any age, uses a second controller to collect stars. This doesn't require a lot of skill, but it gives the young player a sense of accomplishment.
Another great game for all ages is Mario Kart Wii. Up to four people can play at once, and even my 4 year old son can drive a kart, even if he doesn't always stay on the track. The boys have tons of fun with this, and the adults do too.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
