I have had a thought for a while with possibly having advertisements in certain areas of the game that would be non-intrusive, such as at the bottom of the screen in the tower and O-club, along with on the start up screen. (Not the loading screen, but the one where you log into the game)
My thought is that this would help them be able to afford putting in more updates sooner by being able to get some more programmers to work on the game. I know people don't like advertisements, but if it were to add new things to the game faster, I would not complain, since these advertisements wouldn't be obnoxious and in your face during important situations, such as driving a vehicle or flying a plane.
I'm going to give a general example of this. Say they only put a small advertisement banner on the bottom of the screen for things that people in this game would be interested in (joysticks, RC planes, WW2 liturature, etc) that would be no bigger then the radio box that you type into, but underneith the hud, so it doesn't intrude on what you are doing. Now say every time a player veiws the banner the company gets 50 cents per view (I'm not sure how the payments on advertisement work but it's just an example), now if we have 400 people that play the game in a 24 hour period and each one has to go to the tower 10 times due to shoot downs, landing, or other reasons, that would make $2000 dollars a DAY. That would make it very easy for them to be able to add more people to program the game to the team, and be able to get more into the game faster.
Now, I don't know if hitech has already gone into this idea or not, or whether they want to even try, but this is just a rough idea that I've had for a while and decided to get out there.
