Moreover, Hyperion has a reputation of releasing quality products.
I see no reason to doubt why it would be different with OS 4.0.
I've been fearing, that quality of OS4 would be on par with previous game ports by Hyperion, which, by experience, were proven VERY buggy...
Shogo seemed to be "the least unstabile", usually after 2nd install, it installed almost whole game (missing only few textures) and the game itself seemed to be more stabile than the rest - I think, I've managed to play it 1-2hours before crash!
Freespace, on the other hand, seems the worst: Crashes a lot, of course, mostly during mission :-(
That's really a shame, becouse if you ask me, Freespace is the best game Hyperion has ported, if considering only the "quality of the game", not (un)stability...
