Blizzard makes the game on their dime, and then charges us to actually play it. CIG is not making the game unless you pay for it, so it really is a fair comparison.
Your input is truly valuable in the development of Star Citizen since they are creating the game YOU want. They listen and change features once they get feedback (e.g flight model 2.0). If you don't think it is what you want you WILL get a refund.
