Agree 100% with the sibling responses here. This almost never works in my experience. Kids want to play what their friends are playing - I remember feeling this way a long time ago too.
Maybe you are right and it depends on "friends". Me and my 3 other siblings have alwya liked similar gamnes (We are 7 siblings). Being the eldest I might have played a role thats why I thought that one could influence their children's gaming preference.
