First and foremost I felt it was mocking gamers in general.
For example.. "Let's shoot him, I don't give a damn what he's saying, let's just kill him, and start unloading some cans of whoopass SOMEWHERE."
At first, I found that to be kinda' funny... There are plenty of games (Halo included) where I've started shooting at friendlies just to see what happens, and just to shoot something rather than go through all the talking stuff. Didn't you guys try shooting the monitor? or some Marines from time to time?
The fat guys slamming drinks and stuff was kinda' funny too, if you think in terms of gamers, who don't really care about the world they're blowing stuff up in, they just wanna pull the trigger.
The comparison to the real world military was something I didn't like at all. Nor the political tie-ins. It began to feel like a cheesy armchair attempt to make an important political statement, and really only making a fart joke, retarded jokes, and gay jokes. When I was in 2nd grade, I got called to the office for stumbling around pretending to be retarded, saying "Hey look.. I'm the president!!". It was a stupid retard joke, not a political statement at all, and when challenged on it, I admited that I really had no idea what kinda' person the president was, I was just trying to piss some people off, and make the others laugh. That's about all this video was too.
Don't get me wrong, a well executed fart joke will get me laughing sometimes, but all the realworld tie-ins this thing was trying to do just made it look dumber and dumber.. I watched it soley for the Halo tie-in, just to get a laugh at myself, but there was no real substance here.. it was just like those failed Saturday Night Live skits, where the joke goes on WAY past the point it was funny (if it even WAS funny), and you just kinda' wish your life was a little better so you wouldn't have wasted 5 minutes of your life watching the stupid thing.
I wouldn't get the game, but I wouldn't have gotten it anyways. I think their attempt to drag Halo into the mix, was intentional, but all about reaching halo fans, who make up a large percentage of the gaming public. It's a lot like my "retarded president" joke was about reaching the politically inclined... to make me look politically aware and therefore cool and intelligent, while making president fans angry, allowing them to make statements that made THEM look silly for even bothering to make a stand against such a silly attack.
Regardless, it's crap, and a shame they couldn't have made a more positively focused video that would've been cool to watch, and maybe even entertaining. Of course, it probably would've required Bungie's approval at that point, but as Satire, it's entirely legal. Anyways.. Rockstar Games is no newcomer to making enemies sheerly for the sake of getting attention for their games.
