pretty sure way back in the day on a 1up podcast garnet and co openly talked about how MS fostered the relationship with the US gaming press with free Live accounts (and systems?) .
which was a smart move really, and if you consider the state of ps3's online service at launch well ... can't really blame the media for jumping on the xbox bandwagon.
i mean being part of the live community would have given them all a really handy way to communicate, and play those preview versions of upcoming titles etc ....
and we are talking game press here people, can't imagine they are paid well enough to go buy every system, every game, ...every buck they can save is a winner.
AND if you think about yr typical gaming press ...whats the career path look like? they either work there way up the editorial tree, or , find themselves scooped up by a developer in some creative or community role ... that usually happens after being raging fanboys of said dev or company, see shane/david/etc etc
so hell yeh .... totally has to be some bias or leanings. but they can do so while being intelligent about it . and long as they are not straight up telling lies then it makes for fun podcasts. thats why so many people liked the 1up days when shane was around, cause he knew so much factual gaming history.
but yeh, meh ... props to MS for taking advantage when they could. but if sony's online offering is up to scratch this time, and bf4/fifa/madden etc runs/looks alot better on ps4 ... wont take much for bias to change.
the media can't be tooo happy about all these review embargoes for x1 titles right? i mean that has to be frustrating for them, who's imposing those? MS or the game publishers?
