IMO, they should be sticking with what there good at, study sims...
Sorry for dragging this on, but - in what respect is DCS: P-51D
not a study sim?
From where I am standing, it's the deepest
study of the P-51 that has ever been released. And I am not convinced the Accusim one pars it, either. (It gets points for persistence modeling, but falls behind elsewhere.)
Comparing to "Flight", though, is something I'll refrain from commenting much on. My comments would probably not be fit for print. Have you looked at the product at all?
