Star Citizen, the ambitious new space sim from Wing Commander creator Chris Roberts, has surpassed its US$500,000 (AU$483,721) Kickstarter goal.

At the time of writing, the game has gathered US$548,074 (AU$530,244) in pledges from 12,045 backers, and has 25 more days remaining in its Kickstarter drive.

The game was to be funded on Cloud Imperium Games’ own site, but that repeatedly crashed under the weight of fan interest.

Roberts recently partook in a Reddit Ask Me Anything session, where he mentioned that Star Citizen shared much of Freelancer's vision, that boardings of other craft would play out like a first-person shooter, and that individual ships would be comprised of 100-300 parts, with a level of detail not yet seen in a space sim.
