Cute theory but to be honest Project CARS using crowd funding isn't unique anymore and a lot of people are clued in on how Crowdfunding works and how the industry is abusing its use now. Nobody is being forced to buy it, that you are correct about. I wish those involved in the project great luck but its more about the sudden asking of funding out of nowhere when the game is still a shambles for a lot of people, its easy for individuals to say "ive had no issues" but that does not mean they aren't there. Doing a 4 hour race and having the game hang-up because I used one of the in-built features(AI takeover) is not fun or good game design.
Nobody has to find cheap shots to fire at Project CARS, it quite frankly does a good job of finding them itself.
