Saying crowd funding is indicative of a declining market is just plain wrong El.... The fact of the matter is, you need to look at it from the publishers standpoint.... They dont CARE what type of game it is, they CARE about the bottom line when it comes to the dollar. Right now, the money is in FPS games like MOH and Battlefield.... it makes them money... thats all they care about.
Developers who are turning to crowd funding is a GOOD thing. It lets them make the game they want without big brother (ie.. EA) dictating how the game is made based on maximized profits.... And getting the funding they ask for from the "crowd" reinforces this. I agree PC is not the leading game platform anymore, but I also believe that kickstarter and general crowd funding is going to change this. It gives gamers a voice on what they want to play....
All you have to look at is Project Eternity.... A PC RPG in the vein of games like Baldurs gate and Icewind Dale... Breaking the record for a Kickstarter game getting close to 4mil (not including paypal) when the asked goal was just 1.1mil (which was reached in just a few days). The demand is there and its no longer a necesity to pander to HUGE evil companies like EA.... Kickstarter gives a chance for developers to ask the community directly if they want what they are offering and I say thats a good thing.
As far as your thoughts on why Chris Roberts cant get funding for Star Citizen, its because he never asked for it. He specifically stated that he doesnt want the beurocratic bull that comes from a publisher with deadlines and "catering to the masses".... He is making this game because thats what he loves... Thats what helped make the Wing Commander series so great. Relying on a publisher is what made Freelancer so mediocre. He didnt have to rely on a huge game publisher back when he created Wing Commander. When you have an idea for a game, and you see kickstarters like Wasteland 2 and Project Eternity getting millions of dollars from your audience, why go through a publisher who's only interest is the dollar ammount, especially when you can go straight to the source (the fans) and get THEM to fund it?
If it's a bad idea, it wont get funded, if its a wanted product... it will. It's been more than a decade since an "infinity engine" RPG was released.... They are some of the most beloved games in history.... The closest game to come to that in recent memory is Dragon Age: Origin and that was a hit.... Then EA bought out Bioware and things went to . big suprise.

Here comes Obsidian who couldnt get funding from a publisher with Project Eternity so they looked at crowd funding, and lo and behold, they got almost 4x the ammount of funding they were asking for.
As far as Star Citizen, its currently funded 1.3mil with a goal of 2mil and is a few days shy of the halfway mark before its funding period ends.... I have no doubt it will reach its goal and then some.
