It seems that family/kid friendly titles have declined massively this generation.
Disney Infinity is dead, Skylanders & Just Dance have had huge declines but might last another year or two. The return of Guitar Hero & Rock Band failed and probably arent getting new entries.
The only 3rd party kid/family titles that seem to be doing well are Minecraft & Lego titles.
