I'm not sure how much interest there is in video gaming on Hubski (it's not often generative of a great amount of discussion anyway) but I figured that having a Steam group couldn't hurt. And besides, with a growing number of members I can only imagine that more people interested in games will pop up.
It's a public group, so join away. :)

And feel free to add me as a friend if you like.
