Physics will be a big deal in Star Citizen and Squadron 42, as Wing Commander‘s creator Chris Roberts explained in more than one occasion.
The game will include a full rigid body simulation, and we’ll be able to see auxiliary thrusters doing their job to move ships in the right direction since there’s no atmosphere in space to create drag. The developer actually took some visual liberties in order to make things look cooler (as continual application of micro-thrusts isn’t exactly as cool too look at as longer bursts), but everything is correct in terms of simulation. You can read the full technical explanation here.
Roberts also admitted that ships don’t really need wings like the ones displayed by the Hornet shown during the GDC demo, but they simply look good and will be needed with possible expansions involving atmospheric flight.
In the meanwhile the game has collected $1,171,291 on the official site and went past the halfway mark in only two days on Kickstarter, with $266,895 pledged. Can’t say that things aren’t looking good. If you want to pledge yourself (and you should) you can go here or here.
