BenDover,
There are parts of Janes were you can't tell your looking at a simm. I swear they spliced in real WW2 footage.
I haven't played it in a while so maybe my memory is making it seem better than it is. But when your cockpit is hit you can see your wind screen shattered, blood on the glass and oil on the windshield.
Also the textures aren't to bright which gives it a nostaglic look and makes the resolution just seem more real. More like grainy motion picture film instead of animation. You know how the guys here take screenies and make them black and white so you can't tell if it is an old picture or not, just like that.
IMHO all of the modern online simms AH, WB3, CFS2/3 and others all look cartoony to me. Janes looks like a scene from Saving Private Ryan.
