I was thinking of someone like this as well. I am introducing a Mail section where users can send in mail and staff answer it, similar to the Letters section in gaming magazine, kicking off some discussion and giving more contact between Staff and users. But at the moment, nobody's writing any reviews, and the news needs to pick up, so don't expect much fast.
The comic sounds cool, though. If anyone is a dab hand at drawing, I don't think anyone would object to a spot of manga.
