This is a new game developer magazine, the second edition has recently been sent out and has roughly 20,000 users, mostly developers with a couple thousand journalists. It is a free magazine and with that in mind and the fact that it is new, the thin nature of the magazine can be over looked, certainly for now.
It has a different approach to development, a lot of stories from those involved with development, talk of casual games, projects being cancelled and in depth interviews from people behind some game franchises.
What this magazine doesn't have, tutorials and in depth talks in code base, art work or tools reviews. I don't think that is a problem though because there are plenty of other magazines out there which cover this.
Also unlike some other free magazines, this isn't over loaded with advertisements which is quite refreshing, but that could also be because it has quite a small readership right now.
Either way, it is worth checking out and you aren't losing out as it is free, so check out the signup link up top.
