Frankly I don't think gaming would really warrant any hardcore Hiraldo-style journalism. What is there to be done with all that professionalism, except maybe hard-hitting exposes on EA?
I see game journalism as being pretty akin to movie journalism--keeping us up to date with how such and such plans to adapt thisnthat, what new copyrights have been taken out by which company, interviews with the talent, participating in the pre-release build-up, etc.
Even all that aside, the really good game journalism sites (ie The Escapist) are more about targeted, speculative articles written about developments in the industry and where we see things going. This is in stark contrast to, say, more traditional forms of journalism, which are straight fact-finding expeditions with no personal opinion or bias pushing things one way or another (ideally, at least).
I guess I'm really saying that The Escapist is probably more like AintItCool than the New York Times, and I'm not sure there's anything wrong with that.
