http://www.videojug.com/film/how-to-beat-your-children-at-computer-games Some good info there but i think a better way would be: PLAY OLDER 'GOOD' GAMES THEY DONT UNDERSTAND!! (MS. PACMAN,DONKEY KONG,ETC)
I also like these games very interesting and funny games. I am feel good in PACMaN, i can give challenged to anyone in this game. I think every one should pay games only.
Just be spontaneous and try new strategies (that's their main advantage they can adapt faster). gl <3
