I'd agree that I'm more interested in "FM-candy" than low-level eye-candy, though I'd hope to find a good level of both in this particular genre.
While the speeds are quite low compared to WW2 norms I don't think 100 mph is particularly slow. In fact, the closer to the ground you fly the faster it will appear to be, and, if you hit something solid, you'll know what I mean
So, while I'm keen to see trees, bushes and smoke being affected by the wind, I'm far more interested in feeling that effect transmitted to the flight model. It should make 50mph barrel rolls interesting, as long I'm only watching, lol.
