Feature bloat is a common problem with crowdfunded games, and no title I've seen suffers from it more than Star Citizen. Fans want all the things in their game, without thinking much about how they actually tie together into a coherent and satisfying experience. And of course the studio wants to placate the fans to gain their loyalty and attract more backers.
There's also the problem that crowdfunding doesn't encourage you to actually finish the game. Not when you're already making lots of money by releasing tech demos, building up hype, selling outrageously priced ships ''temporarily'' and so forth. You can keep the circus going for years on end. You see it on Steam so freaking much, look at all these Early Access titles that never get finished because there's no reason for them to be finished, the devs already have your money. I'm not saying Star Citizen is 100% in that situation, but it does make one think.
