First, let me say that I own three FSDT airports and am totally satisfied with all three both in quality and choice of subject. I also applaud the choice of Vancouver. Recently I decided to expand my flight sim world and add Europe to my repertoire. Accordingly, I bought FSDT Geneva Cointrin which is great and hope to include Zurich before too long. Wow, some great scenery there!
On expanding to Europe, I soon discovered the availability of many smaller, regional-sized airport sceneries. I find these every bit as enjoyable as the "super-size" airports, but best of all, they provide more opportunity for shorter-hop flights.
I wish we could see more mid-size and smaller airports for the U.S. of the FSDT quality. I can't imagine they wouldn't sell if they fell within the $20 -$25 range. Lots of great subjects begging to be done: Richmond and Reno, Burbank and Birmingham, Tucson, Des Moines, Austin, Jacksonville, Spokane, Albany; tons more.
