Very little overall.  The movie functions are probably the most interesting to me, followed by the music.  But I am disappointed to learn that you can't use last.fm while in-game which makes that feature pretty much pointless for almost every user out there, and I really could give two-shits about the social networking features; I feel they are there for two kinds of people, the casual, and the insecure.  I really just cannot see the reasoning behind why the social features were included, personally.

I am a huge fan of Valve's Team Fortress 2 (on the PC of course!) and as such, making fan art was something that compelled me.  So I made this vector of the spy (my favorite class). Vector, is a fancy word for "scalable graphic" which just means that you can re-size the original to any size and it won't lose any of its quality (like a billboard or something).  Below are 3 shots, 100% size (original size), a mid-level shot, and an extremely close shot (click it to see the full size); these are to show off the detail and demonstrate the properties of a vector (notice how the edges don't get jagged like a digital picture would if you were to enlarge it)  I hope you enjoy!:
 

I don't normally write blogs but I couldn't  pass up the opportunity to share this.... abomination with the GB community.  I was laughing out loud literally when I first saw this thing.  What made it even more hysterical to me was that the person who made this thought it was actually good.  Don't get me wrong there is some good model work going on at the core... but... the face.  Oh my god the face... and those lifeless eyes!  This may be the creepiest fan art ever!  So without anymore prattling from me I present you the female Spy (much larger, scarier version at link provided below):
 


I know I wouldn't mess with her... lol
She probably has more testosterone in her than the 9 male versions of the classes.
Also, I did not make this!  The original thread can be found (with reactions lol) @

I buy downloadable games because anymore they can offer just as much fun and replayability as a AAA title can.  They are less expensive and I can circumvent dealing with any dumbfounded employee that is all too happy to tell me about their latest card or reserve service.  
 
Fat Princess, Trine and Shadow Complex are 3 recent games that demonstrate there are some very high-quality downloadable games out there that have excellent presentation and offer a lot for their price.  More and more come to the market each year and already I feel saturated, but the downloadable games generally offer new ideas too that a AAA title would be too afraid to do.  Downloadable games allow developers more creative freedom with less risk involved.
