everything said about HHG is basically true to some extent. the dude is an unprofessional shill for companies who had been inappropriately using other people's work...
that being said, so is most of the industry. much of HHG's behavior is actually quite common.
one of the only significant differences is his conduct at events. he probably is annoying as hell and rubs his peers the wrong way in person, so they then have even more reason to outcast him.
unsuccessful CACs already are jealous of him, but the more successful ones are basically just annoyed and embarrassed that his ghetto behavior might actually represent them, it only got more intense now that some gaming lobby has made him a spokesman, LOL.
my own feelings, he is too unprofessional to be of use to my interests of getting relatively objective information about games. you cant cross the streams by being a journalist reviewing games that you made songs for. i had to stop following him on twitter because it seemed like all he would do was promote shytty popcorn flicks with video game tie ins every friday, LOL.
his rise to fame is that he is the most shameless person to ever openly tell publishers that he basically will speak positively about every game that ever graces his show. again, other game sites are guilty of it, but they know what conflict of interest looks like, and make attempts to hide it. i view him more as a gaming "personality", and in that capacity i actually think being a spokesman or ambassador is perfect for him. his politically incorrect behavior is actually extremely common among mainstream gamers (just look at the chats of multiplayer games) so he is not giving a bad name to gamers, gamers on average, are actually more crude than HHG
but if he really does want to be the number one journalist, he should research what journalism is and start doing it. and that would also meant to stop getting paid directly by gaming companies or lobbying groups, and be willing to give negative reviews to games that came from companies that either bought ad space on his site or flew him out to their events.
