If its a free game, does that mean people will create their own dedicated servers or host them like TF2 or CS:S. How will you advertise this? You really need to advertise hard to get this out and I suggest if you get to that stage to make small trailers of slight gameplay with information rather than the realistic cutscene trailers we get nowadays for the worst games of the decade. Can't wait for this though, Halo 3 was amazing. Add character customisation and you'll win the internet.
