It did get a bad rep for bugs...but boy it was tough.
Anyway, I thought the gunsight view worked well, very immersive and you actually used the iron sight to aim.
I think this is better than the crosshair on screen.
Remember how in a CQB, the weapon flash from your muzzle would obscure the target when firing....ok, this maybe inaccurate but I thought this approach added to the experience.
Interesting. I never played H&D (what is it?). I only know of one other mod trying to do this & it is a pretty kewl mod but yea the muzzle flash makes it hard to see the target sometimes.. It's called Night's Edge Wet Works for Unreal Tournament.
