Sarah over at Lifehacker has pointed us in the direction of a freshly launched gaming news and reviews site aimed at parents, called What They Play. Intermingled with your standard reviews are articles such as "Wii Found One: The Parents Guide To Finding A Wii" (not such a bad idea considering how hard the damn things were to find last Christmas).
Reviews don't appear to be scored by quality, rather users can rate them based on minimum age. According to the site, Assassin's Creed is appropriate for kids 11 and over.
Okay, it might need a little work.
It wasn't long ago that Oz gaming site PALGN launched GamerKids, its own attempt at such a portal. For now, What They Play looks like the better effort, as long as you don't mind the international feel, particularly the use of ESRB ratings.
I think it's going to take a while for sites like GamerKids and What They Play to find the right formula, but what we've seen so far is definitely a solid start.
