On Flightsim.com I just read and watched a preview of World Of Aircraft Glider Simulator, a soon to be released glider sim. Only a handful of aircraft and only two airports, but a fair chunk of detail. The text gives some interesting basic info, but the 9 minute video shows it to good advantage. I got the impression there would be more versions (probably non-glider) of this in the future.
