Greetings Carl,
Well,about the brightness of the video you are correct,however i think it's more a youtube thing,because if you play the video,before you putted it on youtube,i'm sure it must has been alot brighter.
For the rest,this video is great,it give a nice impression of what you can do with the sim,and what you can expect.
The music is also,great.
You know what you are doing,with making video's.
Marc
