Oh right, that's more reassuring. I guess you'd still have to cut a deal with Valve to use FPs fork commercially though? Which is a wildcard since the licensing terms aren't public as far as I can tell.

That doesn't sound good, maybe they realized after the fact that they haven't actually worked things out with Valve?
My point is, if I were Valve id let Garry run wild with my engine--no deal needed. Hes proven himself more than once. Just a thought!
