Airports seem to sit on green mats with a few fuzzy trees scattered about. The worst though is water. It looks like a cheap blue toupee' with confusing swirls going in different directions. Another disappointment is the lack of decent instrument panels. Like I say, this is the area that could prevent this sim from being a household name so far as flight sims go.
Sound is excellent.
Wind noise is very appropriate and all forty planes seem to have their own unique sound although I'm sure that is not really the case. My favorite overall flight sim. You can build a plane from scratch and see if it will fly. Don't trust my word for it. The biggest thing I can say about this game is that it runs butter smooth.
