Its something we discussed on many a occasion,That would be a waste of time and money for everyone involved. Game development is very cut throat more so in sim racing, a error or two in the physics and this community will butcher you.
if you have some hidden programmer like Stefano in your picket give us a shout,
you can have 50 3D artists, 50 audio guys, and 50 physics guys makes no difference,
if you have no programmers to build the core physics engine from scratch.
