I can't help but wonder if this is a way to keep Flight Unlimited II copies selling. When a sim concentrates on a limited area like this, the detail level skyrockets. You'll find no exception here - the Seattle area is totally breathtaking, with terrain detailed exquisitely. Enough famous Seattle landmarks exist to be recognizable to many, and it's great fun to buzz the space needle in a Fokker Triplane. You need to decide whether a large area in lower detail or a smaller area in greater detail appeals to you, but if you're looking for high detail, this simulation does not disappoint.
Planes look very good, and the cockpits are rendered in wonderful detail.
Panning isn't as smooth as I'd like on a system significantly above the minimum hardware requirements, and I imagine it would take a beefy system indeed to make the scrolling comfortable. Sound effects are quite realistic - the different aircraft have sounds that show their unique characteristics. Pilot voice may be chosen from a list of separately installable models. No flight simulation is worth anything if the flight model is no good, and Flight Unlimited III does a wonderful job. Multiple options are available to limit the difficulty so that the most people can get a high level of enjoyment from the game.
