I can't tell if your objection to the stories is that they weren't incisive and detailed enough -- not "grand" enough to use your word, though I don't really know what you mean by that, as the vast majority of news stories published daily by every major publication aren't exactly "grand" -- or that they were published at all against the likely wishes of the publishers' departments. But it can't be both.
If the former, that's not a reasonable standard to hold any journalistic outlet to. No outlet ever has gotten by solely on publishing detailed exposes of long-running events. For every one of those, there are a hundred shorter and less detailed stories essentially reporting a couple facts and giving some context to them but that don't require talking to dozens of witnesses and writing five thousand words. This isn't true just in games journalism, but in every realm. Again, see my examples of film outlets reporting on which scripts are in development and who's in the running to be cast for which parts. Rumors and insider gossip about such things are reported daily in the film industry, and they don't need 5,000-word stories to do it. Why should they? Sometimes a piece of news is just that.
If the latter, I think it should be trivially obvious why journalists in any field should not be beholden to the whims of PR departments and anyone suggesting that they should has absolutely no understanding or interest in real journalism.
