Jason, well as we have talked about I am in marketing and advertisement so I'll give my two cents for what they are worth.

This is a very good game play video, but way to long for marketing purposes. Try to keep it to 30-45 seconds in length, an absolute max would be 1 1/2 minutes. The normal viewer makes up their mind in the first 7-10 seconds and will stay tuned for up to 45 seconds. Anything more is just filler for a video game and filler makes it look like you don't have much to show.

The 2nd sound track is the best to put the advertisement to. Its up beat and conveys a sense of urgency. Take it and about 20 seconds of the BEST game play and see what you can do. Now add in a 2 second (no longer) title screen, and 3-8 seconds of trail out making sure that your web address is on the LAST frame of the video. That way when the video stops you will be left with the web address for the game.

In case your good at math, I said 2 second lead-in, 20 second game play, 3-5 seconds of lead out. Thats only 25-30 seconds total, try and add in some interesting transitions between screens, NEVER EVER EVER go to a white screen, the color saturates the viewers mind and they will miss the first 1/2 a second after the white transition. Instead go for a flip with black between game screens, or use a slide out, fade to black and fade in. IE Always use black as a filler. It creates a hole in the mind that makes people want to fill the hole, they automatically fill the hole with the next image they see.

Make sure the video is viewable at many resolutions and place it in key locations (IE: boards, blogs, youtube, and on your home page). Also, build out something in flash or silverlight to showcase the game quickly and in common banner sizes. In case you don't know, top and foot ads are typically 468x60px (Width x Height) with left or right block ads coming in at 120px wide and some place between 240 and 320px high.

These ads you should place carefully on pages that will gain attention.

The current video should be placed on your website and places of great interest (gge for example) that will tolerate longer video lengths. Mark it as a GAME PLAY VIDEO and not an advertisement.

As I said before, if you want help with marketing let me know I think you have a good looking product. Now its time to get it in the public eye and see if you can't make a buck or two from it
