AVSIM Online has a review of Jon Patchs excellent Vancouver+ addon for Microsoft Flight Simulator/X. I was on the beta team for Vancouver+ and must say, it's a very cool thing to "fly" over your own hometown and have it not as a random generic set of random building textures, but what you're used to driving through every day.

The review has lots of screenshots to show what you're going to get, including some not 100% desirable effects.
