I don't think the Official magazines are biased in that they just blindly promote 1st party titles, etc. (though i admit some of those exclusive early reviews do seem like mostly puff pieces, with a lot of hyperbole). I get all three too, and they're really writing to an audience that only has one console, so of course they're not going to say stuff like, there are 99 better FPS's out on the other consoles, avoid this one. While I'm sure it's becoming less commonplace, there are people who only have one console and don't care about that.
Actually, out of all of them, I'm impressed by Nintendo Power the most... it's just unfortunate that the main console there has probably the least content I'm actually interested in.
I am surprised that people here say that they got gamerpics and themes recently. I've been subscribing on cheap subs for a while on the disc version of this magazine, and I stopped even looking at the disc long, long ago... when was the last time they had gamerpics or themes? The last one I actually used was Borderlands, and that was some time ago... the last time there was some great DLC that came with the disc, I think it was Ghost Recon 2. You'd think they'd at least throw some Avatar stuff on there, or an exclusive theme or something.
