Two possible strategies (both can be pursued)
1) Focus on pre-teen market. Emphasize non-violence of games and also the local multiplayer allowing parents to play with their kids or the kids being able to play together, as opposed to the solitary online FPSs. An extreme commercial idea might be to have the worst caricature of a pre-teen CoD player screaming profanities and racial slurs and the multiple consoles that need to be bought for each child (or maybe each sibling is playing in their own rooms, even though they're next door).
2) Do a nostalgia campaign. A little bit similar to how Sony's targeting the "players". Emphasize the fact that new games just aren't good anymore and are about pretty graphics. Remind them about all those old school games they enjoyed. Then come out with new releases of Super Smash Bros, Zelda, etc.
Example commercial might be showing college guys in the 90s playing Super Smash Bros, them being bored today, and then all the old friends getting back together playing Smash Bros.
Or maybe pursue both. Gamer dad brings out the WiiU and his son's like "This is boring, I want to play CoD!" and then the dad goes "trust me, give this game a shot" and the two generations enjoy some old school Nintendo gameplay, together.
