Computer and Video Games has an interesting, if short, article about Valve looking into children's games, the Wii and even MMOs:

"There's a lot of people at Valve who are parents and would love to make a game for kids," Valve's Doug Lombardi told us recently.

"We all play the Wii a lot and we think that the proper way for Valve to approach the Wii would be to make something cool designed specifically for it." he added, when quizzed on the possibility of Valve venturing away from its usual FPS scene.

"I mean, I'm not making any announcements", he continued, "but there's a lot of desire internally to do something for kids, do something on the Wii."

Valve has also taken a shine to the MMO scene: "Gabe (Valve co-founder, Gabe Newell) is a huge fan of MMO RPGs and he's always wanted to make one," Lombardi said.

"But that's a big risk to venture out on," he points out, so we wouldn't hold our breath on that one.

There's not a whole lot more at the link above but there is a bit so check it out if you're of a mind.
