Star Citizen's crowdfunding campaign has now reached an incredible $66 million, up from $63 million just one week ago. Funding for the PC game has showed no signs of slowing down, through $3 million in one week is one of the most dramatic increases in recent months. It's unclear what caused the spike.

In all, more than 672,000 people have contributed to the Star Citizen campaign so far. The game is the most crowdfunded project of any kind in history. Creator Chris Roberts is hopeful the title can reach $100 million during its lifetime--a milestone that appears likely, given how fast funding is coming through lately.

Developer Cloud Imperium Games says Star Citizen is hoping to be the first AAA game developed with money from fans instead of a big-name publisher. It seems well on its way to achieving that goal.
