Well hi there,
I hope you get the game going to a point you can start doing proof of concept by having 700+ players in your servers. Massive First person shooters are always fun, be sure to have a solid clan system (<-this is a must for success) and tight shooter mechcanics as well as freedom of choice in charater selection and open sided transports you can shoot out of just a personal preferance there. I wish I could see your video right now but I am at a place were that website is blocked so I will check it out later hope others chime in for you.
